This is a comprehensive History list of the ten versions of Astrolog
that have been released to the net over the past twelve months. This
file is mainly for those who have the most recent version (2.30) but
yet aren't familiar with the earlier versions in which many of the
other (not just added) features were described and documented. Below
is a listing of all versions of Astrolog that have been posted, after
which for each version, is listed the description of the new changes
added to that version. Taken together, all the update descriptions add
up to a comprehensive list of Astrolog's features and command switches.

Astrolog 1.00 posted Wed, 11 Sep 91 00:00:38 GMT
************************************************

There seems to have been zillions of requests for unix system programs
which can calculate planetary positions, or a birthchart in general.
I had been looking all over the place for one for a long while without
success, until someone posted the fact that Matrix software produces a
book called 'Manual of Computer Programming for Astrologers' which
contains all kinds of useful formulas. Anyway, since there doesn't
seem to be an astrology program in existance anywhere, I decided to
make one myself and got the book and converted the routines to C and
made a chart casting program around them. At last here is a program
which can do your chart for you! Cut out the portion of this article
between the "cut here"'s, and compile the program with "cc -O
astrolog.c -lm". Execute it simply by entering "astrolog" (assuming
that's the name of the executable), and the program will ask you for
all the birth info and will give the planet/house positions. (e.g.
for here in Seattle right now for the seven prompts I would enter: 9;
10; 1991; 16.05 [for 5:05pm, with daylight time in effect]; 122.20;
47.36) The program calculates the positions of all planets, chiron,
the four main asteroids, as well as stuff like the part of fortune and
vertex. There are option switches (do astrolog -H to see them) which
allow siderial and heliocentric based charts to be done as well. Enjoy
the program, but remember the copyright message. Yes, I know the code
is currently very messy, but I wanted to get this posted as fast as
possible so we can start calculating stuff right away. I'm currently
adding other features, like aspects, other house systems besides
placidus, an option to generate the chart for this exact moment, etc,
to the program, so expect future enhancements. There's also another
program I have at home which generates nice graphic wheel charts (for
a different computer system) given the birth data (makes nice X11
bitmaps) which I hope to be able to convert soon also. Anyway:

************************************************
Astrolog 1.10 posted Sat, 14 Sep 91 00:02:16 GMT
************************************************

Several changes and fixes have been made to the astrolog.c birthchart
calculator since the first posting four days ago:

Some problems that people had with compiling it have been corrected:
  * The value PI is now explicitly defined, instead of depending on the math
    library which may or may not have defined it already.
  * All line lengths are less than 80 characters, to help prevent line
    splitting or cutting from those whose news servers puke on too long lines.

The minor bug in which the moon's north node was *not* displayed as being
retrograde has been fixed, as well as a rare display alignment glitch.

New features have been added to the program (which may be combined):
  * Aspects and midpoint display is now supported: Invoke as astrolog -g and
    a 20x20 grid showing the midpoint locations for each planet, and showing
    if any aspects are present and how accurate they are, is displayed.
  * A couple of different house systems are now supported: Invoke as
    astrolog -c <number> to change the system from the default Placidus.
    (See astrolog -H for help on what each number refers to.)
  * Additional information is displayed when the chart is cast:
    (1) Whether or not each planet is in it's ruling sign, or fall, as well
        as displaying the same information for ruling or debilitating houses.
    (2) The sum of the signs in each element and mode and their totals is
        displayed in a grid form.
  * For those with unix systems who can handle the time calls (If your
    system pukes on trying to compile this, simply comment out the
    #define TIME line at the beginning), the program now supports displaying
    the chart for the time at the current moment! In other words, invoke as
    astrolog -n and see where the planets are right now. (This is fun - the
    house cusps change 1' about every 4 seconds!) You will need to
    change the #defines for the default longitude and latitude in the code
    though, or else specify where you are explicitly by using the -l switch
    to change the default location.
  * Although minor, some more helpful info is displayed when entering the
    chart data, as well as a header for the columns when the chart info is
    displayed.

Again future enhancements will include: supporting yet more house
systems, and allowing the chart to be displayed in a wheel format on
the text screen (not too difficult) or graphically in an X11 window or
bitmap (will take a lot longer to do, although I've done one already
for a different system), allowing saving charts to files and comparing
them with each other or the current status (transits), allowing
progressions to be specified, and maybe a few other things.

I probably could have done this as a patch, but I don't know how to
pack or even unpack patch files, so I guess that's out of the
question. After a few more versions, I might get this in
comp.sources.whatever, but for now I'm just posting it here because
the program is still relatively new. Anyway, sorry if this is a long
article, but anyway, here is the updated version of astrolog.c (can be
compiled, extracted, as before):

************************************************
Astrolog 1.20 posted Fri, 20 Sep 91 23:56:55 GMT
************************************************

Ok, astrology lovers, here is the new and improved version 1.2 (Third
posting) of the Astrolog birthchart calculator, complete with all
kinds of new features, like allowing computation of transits,
progressions, relationships between charts, printing of house wheel
charts, etc:

First a list of bug fixes over version 1.1:
 1) The glaring bug in which, if you said you wanted the Campanus system of
    houses, you would in fact always get Placidus, is fixed.
 2) The program processed dates during the Gregorian calendar incorrectly, and
    this has been fixed.
 3) The default longitude and latitude were truncated to integers, causing
    loss of a few minutes accuracy in the house cusps when using the -n
    option, which has been fixed.
 4) The program now no longer core dumps if you include too few parameters with
    the command switches.
 5) [I thought I corrected this for the previous version, but there was one
    place where I forgot it] The variable M_PI has been replaced with explicit
    definitions of pi for those compilers that don't understand what M_PI is.
 6) The type 'time_t' has been replaced with just an int, since that all it is
    anyway, and since some compilers don't know the type 'time_t'.

Several people have told me that the north node always seem to be off by about
half a degree. I've been looking into this but haven't found the problem yet.
(I've tried using the 'true' north node, the 'mean' north node, etc.) (Wait for
next version.)

Now a list of all the new neat features Astrolog now provides:
(Remember, do 'astrolog -H' to see a brief list of the command switches.)

 * Seven new aspects have been included, for those who like obscure aspects!
   (Thanks to Mark Martin for giving me the list of their angles and orbs.)
 * The '-A' command switch gives a list of all the aspects, their abbreviations
   as used in the aspect grids, their angles, and their orbs.
 * For those who don't like all these aspects, specifying -A <number> will
   limit the number of aspects (e.g. -A 5 will make charts with only the five
   major aspects listed in them).
 * The aspect orbs have been narrowed for certain bodies like the north node
   for which they are expected to be more narrow.
 * There's been a very minor change to the aspect grids, which will indicate
   whether an aspect is slightly short of exact or slight long of exact.
   If the difference is displayed as "3.5" it means the aspect is 3.5 degrees
   long of exact; if it's displayed as "3,5", the aspect is 3.5 degrees short.
   (i.e. with a comma instead of a period; Yeah, I know that's a hack, but it's
   useful in determining whether the exact aspect just happened or is about to
   happen. (Note that conjuncts are always '.', and oppositions always ','.)
 * Five new house systems have been included which can be specified using the
   -c switch. Astrolog now supports 9 different systems total.
 * The program now supports directing output to, and reading output from,
   data files. The '-o' option will dump all the birth data (the date and
   stuff, not the planet positions) to the specified file. The '-i' option will
   cast the chart based on the info in the file. (This allows you to put your
   birth data into a specific file, and cast your chart whenever you want to
   after that without having to reenter your birth data all the time.)
 * Display of the chart in a nice wheel format is now supported using the '-w'
   switch. (Special error case: If one of the houses gets too 'full' of
   planets, the planet will be put at the beginning of the next house.)
 * There are now three different formats of chart display available: The
   standard listing of planet positions, which you get without any switches;
   the aspect/midpoint grid you get with '-g', and the house wheel you get with
   '-w'. The -e "everything" option will display the chart in all three of
   these formats (Of course the screen will scroll because of all the output).
 * Harmonic charts (i.e. where all the planet positions are multiplied by a
   factor and the chart recast) are now supported via the '-x' option. (e.g.
   -x 3 will make all trines conjunct in the chart displayed.)
 * A secondary progression chart for a particular date can be cast using the
   '-p <month> <date> <year>' command switch. (Note, I'm not sure if the house
   cusps are progressed correctly, but they're reasonably close to what is
   properly expected.)
 * Computing the relationship between two charts is now supported. Invoke the
   program as 'astrolog -r <file_of_person1> <file_of_person2>' and the program
   will give you the relationship between the two charts. Normally, and with
   the -w switch, the program will display person2's planets in person1's
   houses (synastry). With the -g switch, a full grid listing the aspects
   between all the planets of the two charts (with person1's planets on the
   vertical axis and person2's on the horizontal) is displayed (minus the
   vertex, because the screen is too narrow to include it unfortunately.)
   Note that transits can be computed with this by comparing your chart with
   the positions of the planets at the current moment (-n switch). To make
   this easier, you may specify the filename "now" for any file and the
   computer will use the current planet positions instead of looking for a like
   named file. (e.g. 'astrolog -r me now' will compute transits for file 'me'.)
 * The command switch '-t <file>' can be used as a shortcut way to compute
   the current transits for the chart in <file>. (Saves you from having to
   mention the 'now' in the '-r' option.)

Anyway, some new features that we might find in the *next* version
are: Adding the calculation of aspects occurring within a day and at
what times they are exact (like in Jim Maynard's Celestial Guides),
and some Astro-graph routines (i.e. like Jim Lewis' astro*carto*graphy
charts which list where in the world the planets were angular at the
time of birth.), as well as finally cleaning up the messy code. I hope
to make some more clear documentation on how to use the program
(remember, most command switches can be combined!) I've got many of
the major features one might want in an astrology program down now,
but there's still room for expansion: There's still the X windows
chart bitmaps (Andy Gray has shown me a nice Postscript program to
print charts graphically that he's working on.) Anyway, enjoy the new
version of Astrolog (Compile as before)!

************************************************
Astrolog 1.30 posted Wed,  9 Oct 91 03:17:04 GMT
************************************************

Once again, we have a new version (1.30, i.e. the Fourth posting) of
the Astrolog birthchart calculator ready to be used. The main
highlights are some more minor (and not so minor) bug fixes, as well
as some great new features, like the ability to display the exact
times of aspects in a day or month, astro*carto*graphy, etc.

(Note, I've sent this to talk.religion.newage in addition to just
alt.astrology this time, since not everyone gets the alt.* groups,
even though I'm increasing my chances of getting flamed for posting 2K
line articles... I'm really going to have to start posting this in
segments soon, or figure out how to post to comp.sources.whatever;
however, the file is still under the magic 64K bytes in length.)

First, the bug fixes over version 1.2:
 1) The north node is *finally* being computed correctly now. Before it would
    always seem to be off by about 1/2 a degree or so.
 2) The Part of fortune was calculated 180 degrees off about half the time
    before, and this major bug has been fixed.
 3) If Daylight Saving time is in affect, the user must subtract 1 from the
    time value entered. If the person happened to be born from midnight - 1am,
    a negative value would have to be entered. Before it wasn't clear what
    value should be entered. In fact now, one should subtract 1 from the
    integer of the value, and not the decimal value itself. In other words,
    things are processed clearer now in that if the person was born at 12:15am
    with DST in affect, they would enter -1.15 (one less than 0.15) instead of
    having to subtract from the whole value and enter something like -0.45.
 4) (This is more of a new feature than a bug) the program now supports
    multiple display switches at once. In other words, the user can invoke with
    '-g -w' and get the aspect grid and the wheel chart, while before the
    program would only allow one of these to be printed at a time (or else the
    user would have to print *everything* using the '-e' switch.)
 5) Oh, and some of the code has been cleaned up, although not much. Slowly but
    surely, this will become an elegant program :)

A couple of people have emailed me saying that their computer (for
example, Mac's) won't accept command switches on the command line
(like they boot Astrolog from a menu for instance.) Therefore, they
weren't able to access all the features of the program. If this is the
case with your system (or if you just don't like command line
options), then comment out the '#define SWITCHES' line at the
beginning of the code. If you do this, then the program will ignore
any switches and prompt you to enter them manually at the very
beginning of program execution.

Now a list of the new neat features Astrolog provides:
(Remember, it's still 'astrolog -H' to see a list of the command switches.)

 * The '-d' option will take the standard chart information, and for the day in
   question, display the exact times of all aspects that occur. This is just
   like the aspects-per-day as displayed in Jim Maynard's Celestial Guide
   books. (Displayed in local time as defined by the specified zone, with
   general accuracy of a few minutes.) This will tell the times all planets
   make aspects with each other, or change their sign; retrogradation during
   the day will be indicated, but the exact time of it won't be listed.
 * The '-r' option can now be used to generate composite relationship charts.
   Simply invoke it as '-rc <person1> <person2>' instead of just -r and a
   composite chart (i.e. composed of the midpoints of the planets, etc of the
   two charts in question) will be generated.
 * The '-L' option will take the standard chart information and generate the
   astrograph positions of the planets. In other words, this does the exact
   same thing that Jim Lewis' Astro*Carto*Graphy maps do. It will display the
   longitude of where on the Earth at the time in question each object was on
   the midheaven and on the nadir, and the latitude of where the planets
   actually appeared at zenith. Also, for latitude increments of 5 degrees, the
   longitude of where the objects appeared on the ascendant and descendant is
   displayed.
 * The '-E <month> <year>' option will generate a quick ephemeris for the ten
   main bodies for the month in question, useful if you just want to see what's
   happening this month in the sky. It generally is used by itself and not with
   any other options. (Displayed daily for midnight, GMT time.) Any dots after
   a planet location in the list indicate the planet was retrograde at the
   time.
 * The '-T <file> <month> <year>' option will scan the entire month specified,
   and print out any transits that happen, in that month, to the planets as
   listed in the specified <file>. (There will be quite a few, even though
   fast moving objects like the moon aren't looked at, so you might want to use
   this option with the '-A 5' option to limit this to just the major aspects.)
   Again, this option is generally is used by itself and not with many others.
   (The times are in GMT time, and generally accurate to within a half hour or
   so; Try doing it for your birth month and your own chart - All planets
   should conjunct their natal positions at about the time of your birth.)
 * There are a few other minor things that might affect the program, such as
   the fact that by default now, only the major and the 6 main minor aspects
   are taken into account, and that one must '-A 18' if they want to get them
   all, as well as a few minor display changes, etc.

Anyway, I've got many of the more advanced features in the program
now, so the next version (might) start to have X windows support in
it. (And of course I mentioned that I was working on a more
comprehensive help file, part of which I posted, but alas, I was more
attracted to adding new features!) I've obtained access to a nice
world map which could be included to enchance the astro*graph -L
option to make *real* astro-graph maps! And of course, I still want to
eventually have the option to have nicely drawn X birthcharts appear
on the screen. I've run Andy Gray's postscript version, and although
it's still not finished, it does make good printouts. Anyway, enjoy
this new version 1.30 of Astrolog, which you can compile as before
after removing before and after the "cut here's" with
'cc -O -o astrolog astrolog.c -lm'!

************************************************
Astrolog 1.40 posted Tue, 12 Nov 91 01:18:13 GMT
************************************************

This being the 11th day of the 11th month, I figured that this would
be a good time to post the new updated version (1.40) of our Astrolog
birthchart calculator plus a whole lot more program! There aren't
really any new fundamental features, but there are over a dozen
enhancements (many suggested by its users) which make it's operation
easier and more powerful. (Plus of course we have a chance to
eliminate a couple of pesky bugs.)

The actual code is in a separate article, which should be right after
or nearby this one.

A list of the new features and enhancements Astrolog version 1.40 provides:
 1) The ability to restrict the transit (-T) and daily aspect (-d) scans
    to just certain bodies has been implemented with the -R switch. Using
    -R by itself will prevent the asteroids, Chiron, the Part of Fortune
    and the Vertex from being in any of the lists. One may also give a
    list of one or more numbers representing planets to be ignored (e.g. 1
    = Sun, 2 = Moon, 3 = Mercury, etc) so that a complete custom setup can
    be obtained (e.g. -R 1 2 3 4 5 will cause all of the inner planets to
    be ignored). More than one -R switch can be combined (e.g. -R -R 16
    will cause the asteroids, etc, and the North Node to be ignored; the
    first -R gets rid of the asteroids, etc, and the second one deletes
    the North Node.) Also, specifying the same particular body more than
    once will cause it to be included again, or in other words, -R
    <objectnum> complements the status of whether it is to be ignored or
    not (e.g. -R -R 15 will cause all of the asteroids, etc, excluding
    Vesta, to be ignored; the first -R makes causes the asteroids to be
    ignored, and specifying Vesta in the second -R makes it reappear.)
    The -R0 option will cause ALL of the bodies to be ignored, which is
    useful if you are looking for just the transits/aspects of a few
    planets (e.g. -R0 6 7 will cause everything but Juptier and Saturn to
    be ignored.) Combining all these methods can cause whatever you are
    looking for in transits and aspects to be quickly found without having
    to wade through lots of stuff you aren't interested in. (Note: -R will
    also affect what bodies appear in the -w wheel chart, too.)
 2) The -T <file> <month> <year> transits option has been expanded. Putting
    a zero in place of the month will cause the entire year to be scanned,
    which prevents one from having to search each month in turn if they are
    looking for something in particular. (Useful in combination with -R.)
 3) The -T option now includes ALL of one's natal house cusps in the transit
    scans instead of just the Asc and MC. The 11th, 12th, 2nd, and 3rd cusps
    have been added (and oppositions to these and the Asc/MC can be used to
    to determine aspects to the other six cusps.)
 4) Normally the -T option always ignores the moon and does not include the
    transiting moon in the lists because it moves so fast and would cause an
    enormous amount of info. Still, if you are looking for lunar transits,
    specifying the option as -T0 instead of just -T will include the moon.
 5) The -d option can now search the entire month for aspects between planets
    if one so desires. Specifying it as -d0 instead of just -d will go through
    the entire month instead of just the current day. (Combining this one with
    -R allows searching for important aspects, sign changes, etc.)
 6) Both the -T and -d option will display the signs that any planets aspecting
    each other are in, in addition to the aspect itself (e.g. instead of just
    "Jupiter Tri Uranus", we have "Jupiter (Vir) Tri (Cap) Uranus". If a
    particular object is going retrograde, then its sign will be displayed in
    brackets instead of parentheses, and if a particular object is about to or
    has just gone retrograde or direct, then its sign will be in <>'s.
 7) The -E <month> <year> ephemeris option can now be used to display the
    ephemeris for the entire year instead of just for one month. Like the -T
    option, putting a '0' for the month will give the entire year's ephemeris.
 8) The -E option can also display the Asteroids, Chiron, and the Node in the
    ephemeris listing if one invokes it as -E0 instead of just -E. Note however
    that this will make each line more than 80 columns, so this is mainly just
    for printing purposes.
 9) The aspects as listed with the -A option are in a more logical order, from
    the most major to the least. This makes the -A <num> aspect restriction
    switch more useful. (e.g. before -A 2 would restrict analysis to
    conjunctions and sextiles, which isn't all that useful; now the same
    command will restrict to conjunctions and oppositions.)
 A) Note also now that by default only the 5 major aspects are used. If
    one wants the minors, they have to do -A 9, and if one want's ALL the
    aspects, they must do -A 18.
 B) Some header info is printed for the standard chart listing, which includes
    the date, time, and location of the chart being displayed, which of course
    keeps one from getting a whole bunch of printouts confused with each other.
 C) The -f option can be used to "flip" the signs and houses, i.e. display the
    house as a sign position and vice versa. For example having the Sun at
    26 degrees Scorpio, 2/3 way though the 10th house, will cause the resulting
    Sun under the -f option to be at 20 degrees Capricorn, 26/30th the way
    through the 8th house. This can be used to determine how far a planet is
    through a particular house, as well as for Domal chart analysis that
    Mark Kenski has informed me about. Domal analysis is based on the fact that
    for synastry comparisons, for example, a planet in Gemini and one in the
    3rd house can be considered related in a way similar to a conjunction.
 D) The -1 <obj> option can be used to change the houses to force a particular
    object to be on the ascendant. This is useful in casting Solar charts or
    for when the time of birth is not exactly known. For example -1 2 will
    case a normal chart, but the house cusps will be rotated so that the moon
    is on the ascendant.
 E) The -+ <#ofdays> option will cast a normal chart, but one for #ofdays in
    the future (or past if a negative value is given). One use for this is in
    combination with the -n and -d options. For instance, I often invoke the
    program as "astrolog -n -d" to see the exact times of today's aspects.
    However, just before midnight I might want to see what's going to happen
    in the following day, so I would do "astrolog -n -d -+ 1" to see the exact
    times for tomorrow's aspects.
 F) Finally the -q <month> <day> <year> option can be used to cast a quick
    chart for 12 noon on a particular date, using the default longitude and
    latitude. if TIME is defined the current time zone will be determined and
    used, otherwise GMT will be used. Again, one example where this is useful
    is with the -d option, e.g. to see the times of exact aspects on a
    particular date, like your next birthday, your finals, etc.

Now, a list of bug fixes over version 1.30:
 * The midpoint grid displayed in the -g option would cause a coredump if any
   of the midpoints lie between 29.5 deg Pisces and 0 deg Aries, and this has
   been fixed.
 * The -d print aspects in day routine would incorrectly sometimes label a
   planet just going direct as just going retrograde, and vice versa. This
   has been corrected.
 * Attempting to enter a non numeric string when prompted for a numeric value
   in the program will cause a bunch of trash to be displayed on the screen.
   The program now properly tells you that that's an improper input. (Also,
   hitting Ctrl-d at an input will gracefully terminate the program.)
 * Although very minor, before there was one place where a function did not
   return a value. Although it didn't cause any bugs, some compilers would
   complain about this.
 * There were a couple of non-computational related typos in the code and the
   comments that have been corrected (e.g. before at the beginning, the comment
   would tell you to enter the "Longitude N" of your current location before
   compiling. This should of course read "Longitude W".)
 * Finally, those trying to compile Astrolog on PC's and other smaller
   computers said that many of the expressions were too long for their
   compiler to handle. Therefore I have cut down some of the longer expressions
   into multiple lines and have replaced a few of the macros with actual
   function calls.

Expect the X routines to be included in the next version, which will
be split into several program parts, as well as some decent
documentation soon, or at least comprehensive list of all the features.

Astrolog 2.00 posted Wed, 11 Dec 91 07:11:25 GMT
************************************************

Tomorrow Uranus transits my Ascendant at 12 degrees 29' Capricorn.
Combine this with my Saturn trining its natal position yesterday, a
nice Aquarius Moon and a Moon Mercury Sextile this evening, and what
would it be a great time to do?

Behold: here is our next version of our Astrolog astrology program!
The main new things this version 2.00 contains are our long awaited
X11 graphics features and the source code now in multiple files.

The program is divided up into 6 source files: astrolog.h, data.c,
formulas.c, options.c, graphics.c, and driver.c. Each of these files
lies in a separate posting of straight source code which should be
after or nearby this one in the list of articles. There is also a
small unix Makefile for the code at the end of this update article. I
chose to post each file separately in this manner, rather than tar
them, uuencode them, zip them, or make a shell archive from them,
because we always have the issue of non-unix people not having access
to or not knowing how how to extract the program.

The main (but not only) thing added to version 2.00 are the X windows
features, which are generally accessed via the new -X switch and
derivatives of it on the command line. There are two different types
of displays: A standard graphic display of a wheel chart in a window
(with glyphs, aspects in the center, etc) and graphic displays of the
Astro-graph charts (which look almost identical to the
astro*carto*graphy maps from Jim Lewis), complete with all the
labeled lines drawn on a map of the world. There are also other
commands that can be given to the window once it is up and running,
which can do other things, such as continually update the window every
few seconds to the current status (i.e. an extended version of the -n
option) as well as other forms of animation. Note that the program is
still text based, and one can easily turn off all the X features by
commenting out the #define X11 in astrolog.h if they don't have X
windows.

A listing and brief description of the command switches for X windows follow:
 -X:  This is the general switch, which means display a chart in an X
      window instead of on the screen in some form. For example, the command
      'astrolog -i mychart -X' will open a new window and display the chart
      in question in it. (Of course, all the other switches, e.g. -R, -c,
      -1, etc, can be used to change what info is actually displayed.)
      If you use the -L astro-graph switch in addition to this, the
      appropriate astro*carto*graphy map will come up in a window instead
      of the earlier boring list of longitudes. (e.g. astrolog -i me -X -L)
 -Xb: This switch will cause a standard X11 bitmap file to be produced
      instead of putting the graphics in an actual window. This is useful if
      you want to convert the graphics to different formats, e.g. so they
      can be displayed on PC's, etc. Note that -Xb (or any other -X<letter>
      switch) automatically assumes the -X switch above, so 'astrolog -i
      file -Xb' is sufficient (and you don't also have to include the -X).
 -Xo <file>: Normally, for -Xb above, the program will prompt you for the
      name to write the bitmap info to; however, you can explicitly specify
      this filename in with the -Xo switch if you don't want to be prompted.
 -XB: This switch will cause the chart graphics to be displayed directly on
      the root window. This action occurs very quickly since the program
      does not have to write a separate bitmap file and call xsetroot -bitmap
      on it (although one could easily do this if they want to). For example,
      one could put the line 'astrolog -n -XB' in their .xsession file
      and whenever they log in, their background will be set to a chart of
      the current state of the planets!
 -Xr: Normally the charts comes up white on a black background (except on
      some workstations in which this seems to be reversed.) Either way, to
      get the chart or bitmap displayed in reverse video (black on white),
      use the -Xr switch.
 -Xw <size> [<size>]: The default window size is 600x600. This can be changed
      with the -Xw switch. -Xw with one argument n will make an n by n
      window; -Xw with two arguments x and y will make an x by y window with
      the chart centered in the middle. Note that this switch will not affect
      astro-graph windows; to change the size of these use -Xs below.
 -Xs <percentage>: Note that the size of the planet and sign glyphs don't
      change when you change the size of the window. This can cause problems
      for very small windows where the glyphs overlap the rest of the chart
      and for very large windows where there is lots of excess space. The
      -Xs switch can be used to change the size of all glyphs. The valid
      values that can be passed to it are 100, 200, and 300, where 200 is
      the default. Note that this switch is used to change the size of the
      astro-graph windows (because the world map is considered to be one
      giant glyph by the program.)
 -XW: Believe it or not, I painstakingly entered the data for the world map
      used by the program by hand using an Atlas during a long week. If you
      just want to see the map of the world by itself without any
      astro-graph lines on it, use the -XW switch.
 -XG [degree]: Once we have the data for the map of the world, there are
      several neat things we can do with it; for instance, with a little
      trigonometry and clipping, we can bring up a view of a globe, which
      is what the -XG switch does. An optional argument will specify a
      rotation value in degrees to display different parts of the globe.
      (The globe seems to look best for a -Xw window size of around 350.)

The X wheel charts have their graphic information organized as
follows: There's an outer circle showing the signs and sign glyphs,
inside of which is a smaller circle divided up into 5 degree
increments to make determining exact degrees easier. Inside of this is
a circle divided up into the 12 houses labeled with numbers. The
entire chart is divided by two dashed lines through the Ascendant/
Descendant (which is always horizontal of course) and the
Midheaven/Nadir. Inside the house circle are the planet glyphs in
their appropriate positions. Small pointer lines run from each glyph
to just before single dots. These dots indicate the precise locations
in the zodiac of each object. The pointer lines (which are dashed if
the object is retrograde and solid otherwise) are necessary so as not
to have to draw planet glyphs on top of one another when planets are
conjunct. Inside the ring of the single dots, are the aspect lines
connecting these positions. Since the default number of aspects to use
is just the 5 majors, one can determine which aspect is in place just
by looking at the aspect line. The accuracy of the aspect is
determined by the dashedness of the line: A solid line means the orb
is < 2 degrees; a dashed line means the orb is < 4 degrees; a really
dashed line mean the orb is < 6 degrees, etc.

The X astro-graph charts are organized as follows: A map of the world
is shown. The edges of the map are labeled with ruler lines that are 5
degrees apart (with longer ruler lines for more important longitudes
and latitudes, like those that are multiples of 10, 30, etc.) The
equator is labeled with a dashed line. The polar regions of the world
aren't shown; the map shown ranges from 60 degrees S latitude to 75
degrees N latitude. Note that each pixel on the screen represents
exactly one half a degree on the world. (For -Xs 100 the ratio is one
pixel to one degree, and for -Xs 300 the ratio is one pixel to 1/3
degree.) On this map are drawn the lines indicating where on the world
the various planets are angular at the time in question. (Note: you
might want to -R restrict some objects because otherwise the map tends
to get pretty cluttered with lines.) As expected, Midheaven and Nadir
lines are vertical, and the Ascendant and Descendant lines are curved.
Little square boxes on the Midheaven lines indicate the exact zenith
latitude location. Each line is labeled at the top or the bottom of
the screen, showing what planet is in question and (sometimes) what
angle is in question. All Ascendant and Midheaven lines are labeled
at the bottom of the screen, and all Descendant and Nadir lines are
labeled at the top. Each line goes a bit beyond to the top or bottom
of the world map, and then another pointer segment (which is again
dashed of the object in question is retrograde) goes and points to the
planet glyph. There is a capital "A" or "M" under each of the glyphs
at the bottom of the screen, explicitly indicating whether the line is
an Ascendant or Midheaven line. At the top of the screen, however,
there are only the glyphs, but one can still determine whether these
lines are Descendant or Nadir lines based on whether they are curved
or not. Note that not all the Descendant lines are labeled; this is
because some of the Ascendant/Descendant lines actually connect near
the top of the screen and don't actually cross it.

Once the X window in question actually comes up, one can press certain
keys within the window to do certain actions. A list of these follows:
 'H': The most important key. Pressing this will display a help list of
      all the key presses available in the text screen from which
      the window was invoked from.
 'q': Pressing this key will terminate the window (and the Astrolog
      program itself.)
 'p': Press this to pause all updates to the window. This is mainly used
      to freeze any animation (see below) but also has an effect even
      on 'still' windows. In pause mode, the window won't be updated at
      all, e.g. moving another window on top of the Astrolog window and
      then off again or iconifying will leave the Astrolog one blank. Key
      presses will still be accepted in pause mode but their effects won't
      be apparent until one presses 'p' again to continue. The fewer X
      windows calls in pause mode will make Astrolog use less CPU time.
 'x': Pressing this will invert the colors in the window, or in other
      words will do the same thing as the -Xr switch on the command line.
 'T': Normally, there is no actual text printed in the windows. However,
      one can bring up header information listing the date, time, and
      location of the chart in question. Pressing the 'T' key will toggle
      the display of the header text at the bottom of the chart on and off.
 'S': One can manually resize the Astrolog windows using a window
      manager (except when a world map is displayed, in which case resizing
      will have no effect). Pressing the 'S' key will resize any (non-world
      map) window to be a square. This is useful, after resizing charts
      to approximately the size you want, to make them precise squares.
 '<' and '>': This two keys will respectively decrease and increase the
      size of the sign and planet glyphs (as well as resize the astro-graph
      charts) through the three scale factors available. After resizing
      the window you will probably want to use these keys if the glyphs are
      now too big or small for the new chart.
 'C', 'L', 'W', 'G': There are basically four main modes in which a window
      can be in: There are the main charts (wheel and astro-graph) as well
      as the two world displays (the simple map by itself and the globe
      view). These four keys can be used to switch between these four
      modes in the middle of program execution. For example, you can bring
      up your own chart in a window, then press 'L' to see the astro-graph
      chart for the same birth data. Then you can press 'W' to just see the
      world map by itself, and 'G' to see the globe view, after which you
      can press 'C' to return to your original wheel chart.

 'N': Animation! This key will toggle in and out of a mode where the chart
      is continually updated in the window. Entering the animation mode
      will cause the chart being currently displayed to be replaced by the
      chart for the exact moment at the time you are running the program.
      Every second or two, the chart will be updated to reflect the new
      current state of the planets and houses. For large window sizes, one
      can actually see very minor changes in the chart every few seconds.
      With the text 'T' mode in effect, the chart is basically an advanced
      version of xclock, and makes a good window to be left running on
      your display. If you are in the -XG globe display mode, pressing
      the 'N' key will cause the globe to rotate for an impressive display!
 '!', '@', '#', '$', '%', '^', '&', '*', and '(': These nine keys (i.e.
      shift plus the number keys from 1..9) enter into a different form
      of chart animation. Pressing them will cause the current chart
      being displayed (i.e. it will not revert to the current planet
      positions) to continually have a delta time added to it and be
      recast and shown. Pressing '!' will have one second added to
      the chart for every update (slow action unless you have a very
      fast system - the animation will be even slower than for the 'N'
      key). Pressing '@' will have one minute added to the chart each
      time, which makes for a nice display (note that you will definitely
      want to be in the text 'T' mode for these animations so you can see
      what times in the future these charts are being cast for. Pressing
      '#" will have one hour added each time (note that now the house
      cusps are starting to move quickly, so you may want to switch to
      a different system of houses (such as the Equal to keep the
      Midheaven from flopping back and forth) and/or use -1 to put an
      object like the sun on the Ascendant.) Pressing '$' will have one
      day added each time (now you will probably want to start using
      -R to remove fast moving objects like the moon), and pressing
      '%' will have one month added for each update of the window.
      The final keys, shift 6..9 cause years, decades, centuries, and
      millenia to be added each time, and tend to only be used to
      look for long range actions (when will Neptune next enter Pisces,
      etc.) To exit this animation mode, press the 'N' key.
 'r': Press this to reverse the direction of any animation taking
      place. For the '!'..'(' animation keys above, this will cause
      negative times to be added to the chart, e.g. pressing '#'
      then 'r' on a chart cast for noon will cause the next chart to
      be displayed for 11am, then 10am, etc. For the Globe animation,
      this will cause the rotation to reverse direction.
 '1'..'9': The nine number keys are used to set the relative "rate" of
      animation to "n" whatevers. For example, normally the "@" key means
      add one minute to the chart for each update, but press "5" and now
      we are adding 5 minutes each time. For the Globe animation,
      by default the Earth rotates one degree each time; however, the
      number keys can speed this up to nine degrees for each update.

There have been a couple of changes made to the program, i.e. not just
new features but some things in version 1.40 are no longer valid:
 * Before, the program tried to actually use internal system calls in the
   time library to determine whether DST was in effect or not. Since this
   didn't seem to be accurate at all times, and also many people's systems
   didn't have the needed gm_tmoff field, I have done away with it and
   have replaced it with a DEFAULT_ZONE constant set at compile time.
 * Now that we have a particular default time zone assumed, the transit (-T)
   times are displayed in the local zone instead of in GMT, the ephemeris
   (-E) list is displayed daily at midnight local time instead of GMT, and
   the quick (-q) chart is always displayed for noon default time, too.
 * The -T transits and -d aspects in day are now displayed in am/pm
   time instead of the 24 hour cloak. There have also been a few
   spacing and alignment changes to make these times easier to read.

In addition to the X enhancements, there have been a few more features added:
 1) I often use Astrolog to look at and compare files containing charts of
    various people. I have many chart files, so I keep them in a separate
    directory. Since it was always a pain to have to cd into this special
    directory all the time, I have added a DEFAULT_DIR string to be set at
    compile time. Now, whenever the program reads in a chart file with the
    -i option, it will first look in the current directory for it. If it's
    not found there, Astrolog will then look for a file of the same name in
    the special default directory.
 2) Additional information has been added to the standard list of the planet
    positions displayed. Planets in their exalted and debilitated signs
    are noted. In addition to the (R) indicating a planet in it's ruling sign,
    and an (F) for a planet in it's fall, we have (e) if a planet is in its
    exalting sign, and a (d) for a planet in its debilitating sign (which is
    always opposite the exaltation, as how the fall is opposite the ruler).
 3) In addition, the total number of planets in each of the hemispheres
    of the wheel, as well the number of objects in positive/masculine and
    negative/feminine quality signs, are counted. To the right of the element
    table, we have a column of six numbers labeled as follows: "+" is the
    number of "positive" objects (i.e. in Fire or Air signs); "-" is the number
    of "negative" objects (i.e. in Water or Earth signs); "M" is the number
    of objects above the horizon (i.e. in the hemisphere of the Midheaven);
    "N" is the number of objects below the horizon (in the hemisphere of the
    Nadir); "A" is the number of objects in the Eastern half of the sky
    (in the hemisphere of the Ascendant); and "D" is the number of objects in
    the Western half of the sky (in the hemisphere of the Descendant).
 4) The -A option when used by itself will now list the number of each aspect
    in addition to all the other info already there (e.g. conjunct = 1,
    opposite = 2, etc.) This is so one can easily figure out what exact
    number to pass to the -A option when changing the number of aspects used.
 5) Similar to the -A option, the new -O option will list all the planets
    and other celestial objects used by the program, and their numbers as
    recognized by the -R restrictions. This list will also show the zodiac
    signs that planets rule, fall in, are exalted in, and debilitated in.
 6) The -z <value> option can be used to change the default time zone to
    the value in question. For example, you can force the -E ephemeris and
    -T transits to be displayed at midnight GMT time instead of the local
    time with -z 0; or, for the East coast where by default the time zone
    is "5", you can do -z 4 during DST to properly display transits,
    aspects in day, and other lists in the local DST zone.
 7) A "new" system of houses has been added: No houses at all, or in other
    words the Ascendant will always be 0 degrees Aries, the Nadir 0 degrees
    Cancer, etc. Access this by passing the value 9 to the -c option.
    This system is useful for the extended chart animations as described
    above where having houses at all can tend to get in the way, and one can
    even observe the precession of the equinoxes with this system if used
    in conjunction with the -s siderial chart option.

Now, a list of bug fixes over version 1.40:
 * A major bug would cause the input from any eastern longitude (or time
   zone) or southern latitude to produce results slightly off the
   expected values. Fixes on how to correct this were posted soon after
   the release of version 1.40, and they are now included in the code, so
   there should be no more problems. The reason why such a large bug got
   in there in the first place (which *wasn't* in versions 1.00-1.20) was
   that I inadvertently introduced it when I was correcting the earlier
   (now fixed) bug which would produce incorrect results whenever the user
   had to enter negative values for the time, e.g. DST was in effect and
   they were born between midnight and 1am (meaning they enter 0.xx -
   1.00 for DST = -1.xx). Both bugs are fixed now and my apologies for
   the hasty debugging which got it in there in the first place.
 * The moon and north node would always produce zodiac positions for the
   standard zodiac, even if the user specified the -s option. The -s
   option will now yield the proper siderial positions for these two
   objects.
 * Some have commented that there are time zones 13 hours before or after
   GMT, and that the old version would only accept values from -12 to +12.
   The legal time zone offsets accepted by the program have been expanded
   to include these areas.
 * Too much round off in the chart headers displayed for a chart would
   force all time zones offsets to be integers, and this has been fixed to
   properly display non-integer zones. Also, another display glitch would
   occasionally display the person as being born one hour after their true
   birth time. Both of these were only display errors and didn't affect
   the actual results computed.
 * A couple of array sizes in the code have been increased to account for
   the fact that some compilers will only reserve n elements for the array
   type name[n], i.e. space is *not* reserved for the index name[n], which
   would introduce glitches in results for some systems before.
 * The -q "quick" chart option wasn't mentioned in the -H help list of all
   the options before, and it is now.
 * Not really a bug, but I neglected to mention in the list of new features
   for version 1.40 that the -1 "put on Ascendant option", if not given any
   object number after it, will by default assume you mean the sun, and will
   cast a normal chart except that the house cusps will be rotated in order
   to put the sun on the Ascendant.

Anyway, that about sums up Astrolog version 2.00. I confess that this
is my first major X window programming job, and that combined with
splitting the code could produce problems on other systems, so there
might be some needed changes to be made in the code soon. Still,
hopefully each code segment is small enough to be compilable on small
systems. Anyway, there probably will be a version 2.10 in the future:
I would like to include some new features like list the latitude
crossings for the astro-graph maps, and I've only really begun to
explore the graphics possibilities with the charts (like I could print
out the aspects grid and locations with the charts, etc). There are
also a couple of other programmers who have expressed interest in
merging their own creations with Astrolog: for example, Postscript
routines (BTW, you can use the xdpr(1) command on certain systems to
print out the contents of an X window), interpretation databases, etc.
As far as Astrolog and computers go, the future in our own minds has
as many possibilities as the future in the stars! :)

To compile version 2.00, first edit the top of the file astrolog.h,
putting in your own appropriate values for the default longitude,
latitude, time zone, and default directory. Also comment out any of
the #defines which set various features that aren't valid on your
system, such as the X11, TIME, and SWITCHES variables. Then, for unix
systems, run the command 'make' on the Makefile (or you can always
compile by hand: "cc -O -c *.c; cc -o astrolog *.o -lm -lX11" will do
it; just make sure to compile each source file and link them together
at the end with the math and X11 libraries.)

************************************************
Astrolog 2.10 posted Tue, 18 Feb 92 07:59:03 GMT
************************************************

As I post this, we are having the Full Moon in Leo/Aquarius. Identity,
represented by the Sun, is in the sign of computers, unconventional
science, and contribution to humanity; opposite the Moon in the sign
of self-expression. The opposition is occurring in the last degree of
these two signs, building up to the entry into the signs of analysis
and self-transcendence. Therefore, guess what it's a good time for?

Behold: the next version (2.10) of our Astrolog astrology program! It
has been over two months since the last version, however some of the
many new features should make it worth the wait. Some of these
included are: X windows in Color, several new X window chart displays,
lots more progression and aspect support, ability to do transits to
composite and other charts, latitude crossings for astro-carto-
graphy, and other things, along with our standard batch of bug fixes.

As before, there are 6 source files: astrolog.h, data.c, formulas.c,
options.c, graphics.c, and driver.c. Each of these files should be in
a separate posting of straight C source code after or nearby this one
in the list of articles. There a small unix Makefile for the program
at the end of this update article. Again, I am posting each file
separately in this manner, rather than using shar, tar, zip, etc,
because we always have the issue of non-unix people not having access
to or not knowing how how to extract the program. Note however, that
very soon I am going to finally post Astrolog to a formal source group
(comp.sources.misc) as a standard shell archive for us unix junkies,
so it should be available at a 24 hour ftp site soon.

--

Here is a complete list of new features now in Astrolog over version 2.00,
listed in rough order from the most significant to least significant:

A) Color X windows is probably the main new feature added to Astrolog
   2.10. The charts displayed in color are *much* more eye catching than
   the old B/W ones, IMHO. Here is how the colors have been assigned for
   the normal wheel and astro-graph charts: Four colors have been
   allocated for the four elements - Fire = Red, Earth = Brown, Air =
   Green, Water = Blue. The various sign glyphs (and the corresponding
   house labels) are in the color of their element. Planets are in the
   color of the sign of their main ruler. Chiron and the four asteroids
   are Gold, while the north node, and other non-physical objects like
   the fortune and vertex are Violet. Representations of the Ascendant/
   Descendant/ Midheaven/ Nadir (in the astro-graph map lines and
   elsewhere) are in the element color of the corresponding sign/house
   that the angular lines refer to, i.e. Ascendant = Red, Midheaven =
   Brown, Descendant = Green, Nadir = Blue. A few extra things have been
   added for color wheel charts only: dark gray lines marking off each
   house (in addition to the main lines on the horizon and meridian), and
   each degree instead of every 5th degree being marked in dark gray on
   the outer circle (every 5th degree being white). Aspects lines are
   colored too, as follows: Conjunctions = Yellow, Sextiles = Light Blue,
   Squares = Red, Trines = Green, Oppositions = Dark Blue. For the minor
   aspects we have: Inconjuncts/Semisextiles = Brown, Semisquares/
   Sesquiquadratures = Orange, (Bi/Semi)Quintiles = Violet,
   (Bi/Tri)Septiles = Gold, (Bi/Quatro)Noviles = Pink.

B) For color X systems, the new -Xm switch will create all windows in
   monochrome B/W mode, as they were in 2.00. In addition, pressing the
   'm' key within a window will toggle in and out of monochrone mode on
   color systems.

C) Aspect grid windows with the appropriate aspect glyphs can be
   displayed by combining the -g option with the -X option (astrolog -g
   -X). Both the split aspect/midpoint grids labeled down the diagonal,
   as well as the relationship aspect grids between two charts (astrolog
   -r <file1> <file2> -g) are supported. The aspects glyphs, objects, and
   the signs in the grids are in their colors as defined earlier. Like
   the astro-graph windows, these charts can't be resized in the normal
   way unless one uses the '>' and '<' keys. For anything less than the
   largest scale size (achieved with the switch -Xs 300, or by pressing
   '>' within a window) all that will be displayed in each aspect grid
   cell is the glyphs of the aspect in effect, the planet being aspected,
   or the sign of the midpoint. However, once the largest scale size is
   reached, there is room in each cell to display the aspect orb to the
   nearest minute off of exact (with a plus or minus sign indicating
   whether the actual angle is slightly greater than or less than exact);
   the degree and minute in addition to the sign for midpoints; and the
   degree and sign location for each planet that's in the grid.
   Remember, the ASCII aspect grids in earlier versions were rather
   limited, only displaying orbs to the nearest 0.1 degree, midpoints to
   the nearest degree, as well as the confusing '.' vs. ',' for angles
   slightly greater or less than exact (not to mention leaving the vertex
   out for the relationship grids between two charts). Well no longer: we
   can now see *real* aspect grids with Astrolog!

D) The -A display aspects option has been extended to display a brief
   verbal description of what each aspect glyph look like. This is in
   case one doesn't know what aspects the weird symbols in the -g -X
   displays are referring to.

E) A new text display switch has been included, -Z, which prints out
   where each object is on the local horizon in terms of altitude and
   azimuth. For each object, the following is displayed: Its altitude on
   the local horizon from +90 degrees (straight up) to -90 degrees
   (straight down), and its azimuth from 0..360 degrees, where 0 = due
   east, 90 = north, 180 = west, 270 = south. To make visualizing the
   azimuth easier, an "azimuth vector" with a N/S component and a W/E
   component is displayed, e.g. (1.00s 0.33w) means that the object is
   mainly south, with its true angle being formed by an vector component
   west that's 1/3 the strength of the south component, i.e. the object
   is about 18 degrees west of south. This along with the altitude should
   make it easy to physically point to where any planet is at any moment,
   making it easy to locate planets in the night sky. This feature can
   also be used to determine the times that a planet rises and sets.
   Also displayed are altitude and azimuth differences between each
   object and the Sun and Moon, first showing the number of degrees that
   the Sun/Moon is "ahead" (or farther east in the zodiac) of the object
   in question, and then the number of degrees that the Sun/Moon is above
   the object in question. This feature can be used to roughly predict
   eclipses! Both the Sun and Moon span about 0.5 degrees in the sky,
   therefore if both the azimuth and altitude differences are < 0.5 (or
   1.0 if the difference is between the Sun and Moon themselves) then the
   object in question is probably being occulted somewhat by the
   Sun/Moon. Note that there are three types of planetary position
   displays: Right ascension and declination showing the object's
   position with respect to the stars, longitude and latitude showing
   where on the Earth the object is straight up (as in the astro-graph
   zenith locations), and finally azimuth and altitude showing the
   positions of the object relative to the local horizon.

F) This new -Z local horizon feature can be displayed in an X window
   as well (e.g. astrolog -Z -X), in which all the planets will be
   displayed in a window depicting the sky. The small dot above or below
   each glyph indicates exactly where each planet is. (Some of the glyphs
   may be overlapping, although the program tries to cut down on this.)
   There is a horizontal line dividing the window representing the local
   horizon; planets above this line are visible, while planets below it
   are set. There are three vertical lines dividing the window as well:
   The middle line represents the due south direction, the one to the
   left is due east, the one to the right is due west, and the edges of
   the window are due north. Like the standard chart display, this window
   may be resized to any proportion. One can press the 'Z' key in any
   window to enter this display type in that window at any time.

G) Ability to write the actual sign and house positions of a chart to
   a file (instead of just the time and place) has been implemented via
   the -o0 <file> option. This option can be used interchangeably with
   the old -o output to file switch. The information written includes the
   zodiac position of the 20 main objects, their retrograde status and
   declination, as well as the positions of the (first six) house cusps.
   This file information can easily be passed into another program, and
   can be read back into Astrolog with the -i option. The -i option will
   automatically determine which type the file is, and will either use
   the given positions, or else calculate them as needed (note that some
   switches, such as the -c house system selection, will have no effect
   for this new file type.) Check an example of one of these files to see
   the precise format (a zodiac position is recorded as three numbers:
   degree in sign, sign as 1..12, and floating point minute within
   degree.) When the files are read back in, they will be flagged as
   "having no space or time" like the composite charts in the chart
   header displays.

H) The new file format can allow one to do things such as transits to
   composite charts (send the composite chart to file with -o0 option and
   then use that file as the first parameter to the -T option) composites
   between two composite charts (use -rc between two composite charts
   sent to a file) and even, if one is willing to do a small amount of
   editing, to do transits to midpoints or the 0 degrees Aries point.
   Note that one can easily edit the positions in the -o0 position file
   to be whatever they like, so one could replace some unimportant object
   (like the vertex) with 0 degrees Aries or an important midpoint value.
   Note that trying to still use the -o time and space output with an
   output chart that doesn't have space/time will confuse the program; it
   will either say it can't make the file or else will output the
   time/space of the most recent parameter file it read in.

I) Another file output feature, the ability to concatenate "comment
   lines" at the end of a data file, been been added to both the -o and
   -o0 options. (Some people have complained that the info in the
   Astrolog chart files are too cryptic.) After scanning the filename,
   the -o[0] option will then write any parameter that follows it at the
   end of the file, until a parameter beginning with a '-' (the next
   switch) is reached. For example: -o 'file' "Walter D. Pullen" Seattle
   will add my name and my birth city in two separate lines at the end of
   'file'. (In unix, quotes can be used to allow spaces within one
   parameter.)

J) Determining dates of transits of progressed planets to natal
   planets can be done with the new -Tp <file> <month> <year> option.
   This is just like the -T option, except that the exact aspects of
   progressed planets (rather than transiting planets) to the planets in
   'file' are displayed. Again, one can substitute '0' for the month to
   scan the entire year.

K) Another added progression feature allows determining aspect times
   of progressed planets among themselves. The -i <file> -dp <month>
   <year> switch will, like the -d option, display times of aspects and
   sign changes, except that they will be for the chart in file,
   progressed throughout the month specified. Progressed planets move
   very slowly ("year for a day") so therefore there will usually be, if
   any, only a couple of aspects in a given month; again, one might want
   to substitute '0' for the month to scan the whole year. Also, since
   they move so slow, the accuracy is cut down, do the dates given are
   probably only accurate to the nearest day, in spite of the times given
   to the minute. Note that Astrolog can now scan for aspects of:
   transiting planets among themselves (-d switch), transiting planets to
   natal planets (-T switch), progressed planets to natal planets (-Tp),
   and progressed planets among themselves (-dp). Only thing Astrolog
   can't do is do progressed planets to transiting planets, although that
   may change in the next version :)

L) The new -pn switch is like the -p <month> <date> <year> switch
   except that (like the -n switch) it assumes the current moment now to
   cast the progressed chart to. This is just another shorthand
   convenience to see what ones progressed chart is like presently; just
   do: astrolog -i file -pn.

M) Determination of latitude crossing points has been added to the
   astro-graph routines! The new -L0 option will do the same thing as the
   -L option, except that after displaying the longitude and latitude
   locations of the Asc/Desc/MC/IC lines, it will then search among the
   lines and display (in order from farthest North to farthest South) the
   latitude of any points where lines cross each other. This includes the
   curvy Asc/Desc lines crossing the straight MC/IC lines as well as
   cases where different Asc/Desc lines cross themselves. And unlike Jim
   Lewis' astro*carto*graphy, Astrolog will also display the longitude of
   the crossing (useful for Asc/Desc crossings) in addition to the
   latitude (as well allowing more planetary bodies to be included in the
   scan, and going farther North and South than Jim Lewis' printouts go.)
   Note however, that there is presently a small (very rare) minor
   omission glitch in the code, where if a crossing is within a couple of
   degrees of 180 deg W/E, it may not be displayed.

N) Change the default orbs of the various aspects with the -Ao <orb1>
   <orb2>... <orbn> switch. Do you not like the 7 degree orbs for
   conjunctions that are in there by default? One can change the first n
   aspect orbs (i.e. as many orb values that one puts after the -Ao)
   anywhere from just the conjunction to all 18 aspects. Non-integer
   values are allowed of course. Use negative orb values to completely
   eliminate an aspect from ever appearing. For example: astrolog -A 6
   -Ao 5 5 -1 10 narrows the orbs for Conjunction and Opposition,
   completely eliminates the Square, widens the orb for Trines, and
   leaves the Sextiles and Inconjuncts in the default values. Note that
   for very wide orbs more than one aspect may apply for a particular
   angle, in which case the more fundamental aspect is chosen. Also for
   wide aspects the decimal value of the orb may be lost in the -g text
   grid (due to too many characters) and their might be some slight
   overlap in the X window -g cells.

O) Note that Astrolog imposes restrictions on the max orb that any
   particular aspect can have to certain particular objects, namely the
   node, fortune, and vertex, which can't have aspects to them in excess
   of 2 degrees. One can suspend these restrictions by replacing the -Ao
   <orbs> option above, invoking it as -AO <orbs> instead. For a fun (and
   perhaps useful) display, try: astrolog -A 1 -AO 180 -g [-X], and see
   everything conjunct everything else.

P) Search through the aspect grid for major aspect configurations,
   including Grand Trines, T-Squares, Grand Crosses, Yod's, and Cradles
   with the -g0 option. This option will produce the same aspect grid
   that -g displays, but afterwards will go through the grid and list any
   of these aspect configurations and what objects are forming them. Of
   course, to see any Yod's, one has to -A 6 or more so that Inconjuncts
   will be included in the aspect grid.
   
Q) Display the locations of the "Uranian" planets with the -u switch.
   Transneptunian or Uranian planets are an interesting subset of
   astrology which includes various objects alleged to be beyond Pluto
   (or something like that, I'm just the programmer). Anyway, Astrolog
   can display the zodiac positions of these bodies as well, and will do
   this by taking the eight Uranian bodies and literally replacing
   Mercury..Pluto with them. (Do: astrolog -u -O to list them.) This
   replacement will allow the Uranians to be included in Astrolog's
   various options, although of course this means that they can't
   interact with Mercury..Pluto in any way. (Note, I didn't bother to
   change the X glyphs or sign rulerships since I don't know what they
   are for the Uranians.)

R) Decan displays are now supported in Astrolog, and one can display a
   decan influenced chart with the -3 switch. The decan theory is that
   each sign in the zodiac can be divided into three parts: The first 10
   degrees (i.e. the first decan) is mainly influenced by the sign in
   question, the second 10 degrees (second decan) although still
   influenced by the sign in question is also somewhat influenced by the
   next sign of the same element, while the last decan is influenced by
   the third sign of the same element. The -3 switch applied to a chart
   will move each object into the sign of its decan. For example, if the
   Sun is at 29 degrees Aquarius and the Moon at 5 degrees Virgo, in the
   resulting chart, the Sun will go to Libra (26 degrees) and the Moon
   will remain in Virgo (although be at 15 degrees now since it was
   previously in the middle of the first decan of Virgo.)

S) In the -w text wheel option, the objects in each house are printed
   from top to bottom in order from earliest in the house to latest. This
   looks good except for in houses 5..8 where this appears backwards
   (i.e. a planet having just entered the 6th house from the 5th is
   displayed right under the Descendant.) Replace -w with the -w0 switch
   and the objects from houses 4 through 9 will be reversed and printed
   in order from bottom to top, making a more flowing looking chart.

T) The new -q0 <month> <date> <year> <time> option takes the four
   parameters and casts a chart for the time in question. The time zone
   and location are taken from the default compiled values. This is just
   yet another useful shorthand way to quickly make a chart. Note that
   this is just like the -q <month> <date> <year> option except that -q
   always casts it for noon in the default zone. Also note that the -a
   option which takes all seven chart parameters can be duplicated with
   -q0 along with the -z <zone> and -l <long> <lat> options.

U) A couple of new compile time option variables have been added to
   the include file astrolog.h. For those people who don't like Placidus,
   a new default house system can be set to the value from 0..9
   indicating what system to use if the user doesn't explicitly specify
   it with -c, Another thing: It must be mentioned that although the
   accuracy of Sun..Pluto and Chiron are to the nearest minute for years
   1900-2000, the four asteroids are relatively inaccurate and can even
   be a couple of degrees off in the worse case. Also, some people just
   don't like or care about the minor bodies. If you don't want these
   values to appear by default, there is a new #define that can be
   commented out so that it will be as if -R is always included when the
   program is run. (Simply do -R to get them back if you compile it this
   way.) There is a new feature added to all the X window displays which
   can toggle the restriction status of the asteroids and other minors.
   Press the 'R' (restrict) key in the window and the screen will be
   redrawn with the restriction status of these toggled.

V) The -Xn [<value>] option can be used to start up an X window in
   animation mode. Before, one would have to explicitly press 'N' or a
   shift+number key to start the window animation. Without a parameter
   after -Xn, the option will start it up in continuous update to "now"
   mode (which is like pressing 'N' in that any chart will be erased with
   the current chart now.) The switch can accept parameters from 1..9,
   corresponding to the animation rates obtained by pressing shift 1..9
   in the window, i.e. update whatever chart is passed to it seconds,
   minutes, hours, days, months, years, etc. later each time.

W) Familiar with ley lines? They are energy lines crossing the Earth.
   I was experimenting earlier with the master ley line grids on the
   Earth (in the pattern of an overlapped 20 sided Icosahedron and 12
   sided Dodecahedron) and I figured Astrolog with it's world map would
   be an interesting program to explore this with. The -XW world map
   display option is always still, and can never be animated. If however
   one tries to animate it, either by the -Xn switch or pressing 'N' in
   the window, a new display showing the ley lines will be shown.
   Actually this is mainly a hack, but I figured I would leave it in
   there for amusement and inspiration. Hackers note: there is an
   interesting "bug" that can arise with the -XW as well as the -XG (and
   -XP, described below) switches: These displays can be brought up
   without having to specify an actual chart. Now suppose one presses
   'C', 'W', etc. to bring up a chart - what will be displayed? The
   answer will be whatever default values were already there, and if
   you're curious, I set to be the time of the New Moon on 1-4-1992 at
   11:11pm GMT at Greenwich England. (i.e. one week before the 11:11)

X) The -XP option will generate a polar view of the Earth as a globe.
   This is like the -XG globe option except that the view is from the top
   (or bottom) and therefore doesn't rotate. By default, the view is
   looking down on the north pole with 0 deg W/E toward the bottom of the
   screen. To see a (fixed) view of the south pole hemisphere, go into
   animation mode. Again, like with all the other X window display
   options, one can enter this display with a keystroke: press 'P' in any
   Astrolog window and it will revert to this display.

Y) A couple of conveniences for the X window features have been added.
   Note that the -Xo <bitmapfilename> option is only used in conjunction
   with the -Xb write output to bitmap switch. Therefore, I have -Xo
   automatically assume -Xb is set. (Invoking -Xb itself without -Xo will
   have the program prompt the user for the bitmap filename.) In other
   words, astrolog -Xb -Xo 'file' is the same as just astrolog -Xo
   'file'. (This may change if I add other file types, but for now none
   are planned.) Also, I should mention that Astrolog includes it's own
   appropriate bitmap if one iconifies the window, instead of reverting
   to the braindead UnknownIcon as it did before.

Z) A few other minor things have been done to the program, such as the
   -H help switch displays more information (e.g. what the difference
   between -T and -T0 is) as well as mentioning for X that you can press
   the 'H' key while within the X window to get a list of all the neat
   things you can do in window once it's already been created.


I could have added a bunch of other features to this version, but as
you can see, I ran out of letters :) Oh well, wait for version 2.20!
Remember now that the -e everything switch includes a lot more chart
information in it since there are more features now.


Here is the list of bug fixes over version 2.00,
listed in rough order from the most major to the least major:

1) I inadvertently disabled the -p progression option while updating
   the program from version 1.40 to 2.00, so that it would produce
   progressed charts way off. This has been fixed and the program
   produces those charts as well as it did in version 1.40 and before.
2) There was a bug in the midpoint routine which would yield results
   180 degrees off occasionally when the two points being passed to the
   routine were themselves almost 180 degrees apart. This would mainly
   affect composite charts and the midpoint grid. This has been fixed for
   all cases now.
3) Some composite charts where the house cusps in the two charts are
   almost 180 degrees apart would have the composite cusps in
   non-sequential order, 180 degrees apart from where they should be,
   e.g. two opposing cusps could be interchanged. The program now makes
   sure this won't happen, and takes corrective measures if necessary.
   Also, composite charts are no longer displayed in the chart headers
   with a bunch of 0's for the date, time, etc. Composite charts are
   properly labeled as being such, while only charts that exists in
   space/time will have their coordinates printed.
4) Some of the values in the header displays, such as time, long/lat,
   etc, would occasionally be displayed one number higher than they
   should be, due to improperly rounding up. This has been fixed. A few
   other minor display areas have been fixed, e.g. in the heliocentric
   planet list -h -O, Earth was abbreviated as "Eart" before.
5) In the -w text wheel option, the objects in each house are supposed
   to be printed from top to bottom in order from earliest in the house
   to latest. The program did this correctly except for cases in which a
   house spanned 0 degrees Aries, in which case the Aries planets would
   be printed before the Pisces planets. This should be the other way
   around, as it is now.
6) I probably should have made the -g text aspect grid and the -E
   ephemeris display be able to be affected by the -R restrictions. They
   weren't before and they are now.
7) Some of my very bad X windows programming in version 2.00 has been
   cleaned up, as least slightly. The program no longer core dumps if the
   DISPLAY environment variable isn't set properly. Before, the windows
   would come up white on black on some machines, and yet black on white
   on others; now as expected everything will come up white on black
   unless one specifies otherwise with the -Xr switch. Finally, a couple
   of people have mentioned that version 2.00 would eat up *lots* of cpu
   even while doing nothing (unless in 'p'ause mode). Also while in pause
   mode, uncovering part of the Astrolog window would leave that part
   blank until pause mode was left. Now, Astrolog doesn't eat cpu unless
   it's doing something useful, and it will always redraw its windows if
   unmapped.
8) Some things that caused problems for PC users have been corrected;
   Astrolog now is explicitly declaring 32 bit longs in places where the
   PC assuming 16 bit ints would cause problems, as well as eliminating a
   couple of unnecessary declarations and adding some more declarations
   which aren't necessary for unix but would confuse a PC.

Note for PC users: I have tried to make this program as much
executable on personal computers and other non-unix systems as
possible. Although this version should be easier to compile than
previous ones were, still there are probably some things I've
forgotten/left out. For instance, for as least one person the
options.c and formulas.c files were too long in version 2.00 and had
to be split again, so one should be aware of these possible factors.

Unfortunately, I am graduating in a little over a month from now, and
therefore probably won't be able to work on or support Astrolog much
unless I can get another account somewhere. Still, I hope to release
an Astrolog 2.20 in another month, perhaps including features like
fixed star tracking. (Have you Sun conjunct the Pleiades? Find out!)

I wish to express thanks to the many people who have pointed out the
bugs (and have made suggestions for new features) in this (as well as
previous) versions so that they could be corrected. You know who you
are! :) As the Sun leaves Aquarius after the Full Moon let's remember
the power of unified effort; and of course the Sun will soon be back
in Aquarius, perhaps next time in the Age of Aquarius!


************************************************
Astrolog 2.20 posted Wed,  3 Jun 92 00:25:40 GMT
************************************************

This file describes the new features, changes, and bug fixes in
version 2.20 of Astrolog (over the previous version, 2.10, posted 3.5
months ago). Although this new version is a stand alone program, this
Update file requires knowledge of the features of version 2.10 in
order to make sense. If you aren't familiar with version 2.10, get and
read the version 2.10 Helpfile which describes all its features from
the alt.astrology ftp site at hilbert.maths.utas.edu.au, or from any
comp.sources.misc archive.

Just some of the new things contained in Astrolog 2.20 are: Fixed star
positions, spatial astronomical charts of the solar system, and a
couple of other things non-astrologer astronomers would like. Also
added are new kinds of and more support for relationship charts, and
the nascent beginnings of an interpretation feature, along with other
things non-astronomer astrologers would like. Ability to scan a data
file for program defaults has been added, allowing changes to be made
to the program without recompiling, along with a bunch of funky
additions to the X graphics features.

----

Important: A few changes have been made to the program, i.e. not just
new features but some things that were true for version 2.10 are no
longer valid. A list of these changes follows:

1) First of all, every object (planets, minor house cusps, uranians,
   and stars) has its own "number", displayable in the -O list. No more
   ugly hacks of overwriting some planets with the uranian positions in
   the -u option. There is virtually no difference between a planet and a
   house cusp. The default is still the first 20 objects to keep the
   charts looking the same as before, although one can have a chart with
   all 78 objects (one for each tarot card ;) if they like. For example,
   the -u uranian switch will now display the uranian locations after
   everything else in the standard chart display. You get what you ask
   for, and what you don't want must be explicitly -R restricted.

2) As a result of the above, the minor house cusps (11th, 12th, 2nd,
   3rd) are no longer included in the -T transit list by default. If you
   want them, you must explicitly specify you want them (with the -C cusp
   option described later). Also, the relationship chart aspect grid now
   includes the vertex (before it only included the first 19 objects) and
   as a result the display will unfortunately exceed 80 columns, unless
   you explicitly restrict one of them with the -R option.

3) The program now makes a distinction between synastry charts, and
   the actual comparison between two charts. Before the -r option would
   combine the two charts in synastry, unless it was the -g option, in
   which case the contents of both charts would be compared in an aspect
   grid. Now -r is only for synastry, and combinations such as "-r chart1
   chart2 -g" or "-r chart1 chart2 -g -X" will display the aspects within
   the synastry chart itself. To actually have two charts side by side,
   use the -r0 option described later, instead of -r.

4) To display the ley lines in the -XW world map window, or to see the
   southern hemisphere in the -XP polar chart, one had to enter animation
   mode before, a hack which of course had nothing to do with animation.
   This "bonus information" is now in a separate feature, accessed with
   the -Xi switch described later.

5) In an X window, pressing the 'S' key would resize the window to be
   a square, and the 'C' key would revert the mode back to the standard
   wheel chart. These two keys presently do other operations described
   later, and the above functions are now accessed by the 'Q' and 'V'
   keys respectively.

6) The chart information at the bottom of the window is now included
   by default, while before it wasn't. To remove it, press the 'T' key in
   the window or use the -XT switch described later.

7) The -w and -w0 switches both display the same text wheel chart, but
   in slightly different ways. They have been reversed in function, since
   the -w0 chart looked better.

8) The "default" chart, i.e. the initial values in the chart
   parameters that are used if one forces a chart to be used when one is
   not expected, e.g. combining the -XW and -o switches, has been
   changed. Before, I had put in the data for the 11:11pm GMT New Moon on
   1-4-1992, but now I have changed it to the chart for this version of
   Astrolog itself: 5-31-1992 9pm PDT Seattle, WA.

9) Finally, concerning the source code itself, there are two new
   files: options.c has been split into the new file charts.c, and
   graphics.c has been split into the new file xcharts.c.

----

Now, a comprehensive list of the features and extensions added to this
version of Astrolog follows:

A) -S switch: A new chart type is available - solar system space
   charts, which give the astronomical positions of each planet in terms
   of x, y, and z coordinates. Although not directly useful
   astrologically, it does give one a good view of how the planets
   actually were positioned at the time in question. For example, normal
   astrology doesn't make the distinction between the four different
   "forms" of say, a Mercury Venus Conjunction, i.e. they can either be
   Conjunct on the near side of the Sun, Conjunct on the far side of the
   Sun, or one can be on one side and the other on the other side. When
   the chart is actually displayed, for each body the following
   information is printed: The relative angle of the planet with respect
   to the central body, i.e. its zodiac position converted to the
   appropriate number from 0..360. This is followed by the x, y, and z
   coordinate positions of the object, in astronomical units from the
   central body. The x-axis increases in the direction of 0 degrees Aries
   (tropical zodiac), the y-axis increases in the direction of 0 degrees
   Cancer, and the z-axis is with respect to the Earth's orbit (meaning
   that the Sun and Earth always have a z-axis value of 0.0). Finally the
   overall length from the central body in AU is printed, which is just
   the diagonal as indicated by the x, y, z vectors. (The Earth and Sun
   are of course always about 1.0 AU from each other.) The Moon circles
   the Earth and isn't a part of the solar system proper; therefore, it
   is never in these charts. The -e everything option will include this
   chart in it's listing of all the chart displays.

   The -S switch can be combined with -X to give an X window chart of the
   solar system. This will be displayed as an aerial view of the entire
   solar system, with 0 degrees Aries to the left of the screen, and 0
   degrees Cancer to the bottom. Note that this chart includes all
   possible planets, including the Earth (whose glyph is a cross inside a
   circle). Whatever object is chosen to be the central body is at the
   center of the screen, with all the others around it. This is a fun
   chart to animate - watch the planets go around the Sun, and *see* how
   they turn retrograde with respect to the Earth. In addition to the
   bodies themselves, twelve spokes are drawn from the center body to the
   edge of the screen, which delineate the zodiac with respect to it.
   Note that the scale of the solar system is large; attempting to fit
   all the planets out to Pluto on the screen at once will cause all the
   inner planets to be crammed together near the middle of the screen. To
   deal with this, the scale size as indicated with the -Xs switch and
   the '<' and '>' keys will affect how much of the solar system is
   viewed at once (in addition to the glyph sizes). For a scale size of
   300, the viewport will have a radius of 6 AU (about out to the orbit
   of Jupiter; useful for viewing the inner planets). For a scale size of
   200 (default), it will have a radius of 30 AU (enough to include
   Neptune, and Pluto most of the time). Finally, a scale size of 100
   will result in a radius of 90 AU, enough to easily include the entire
   solar system, as well as the orbits of the alleged Uranian bodies
   beyond Pluto.

B) -I switch: Another new chart type is available - interpretation of
   influences. This is the beginning of a general interpretation ability
   for the program, although all it does now is calculate the relative
   "power" of each planet's placement, giving a general idea of the
   prominent areas of a chart. When such a chart is printed, each planet
   is given a point value, larger numbers indicating more strength. Each
   planet's strength is divided between two fields: the positioning in
   and of itself, and the power of the aspects it makes with the other
   planets. In addition to each field, the total of these two areas is
   printed, as well as the relative percentage of the planet in question
   with respect to all the planets combined. Each planet gets a ranking
   for its positioning, aspects, and total power as well, with the
   strongest getting #1, the next strongest #2, etc. The -e option will
   include this chart as well in it's listing of all the chart displays.

   To determine the strength of the positioning of a planet, various
   things are taken into account: 1) The power of a planet in and of
   itself, e.g. the Sun and Moon are more powerful then the other
   planets. 2) The house placement of a planet, e.g. a planet in the 1st
   house is more powerful than one in the 2nd. 3) Whether a planet is in
   the sign it rules or is exalted in, e.g. Jupiter in Sag results in
   more power to Jupiter. 4) Whether a planet is in the house
   corresponding to the sign it rules or is exalted in, e.g. Jupiter in
   the 9th house. 5) Planets get more power if the signs they rule are
   occupied, e.g. a bunch of stuff in Aquarius gives more power to
   Uranus. 6) Planets get more power if the houses they rule are
   occupied, e.g. a bunch of stuff in the 11th house gives power to
   Uranus. 7) Finally, planets get power according to what houses the
   cusps of which fall in the signs they rule, i.e. the ruler of the
   Ascendant (and to less extent the Midheaven, and so on) gets lots of
   influence. Determining the strength of a planet's aspects is much
   easier, and is basically composed of the sum of the strength of each
   aspect the planet makes. Taken into account are: 1) The inherent
   influence of the planet being aspected to, e.g. Sun conjunct Jupiter
   gives more influence to Jupiter than Mercury conjunct Jupiter would.
   2) The influence of the aspect itself, e.g. Oppositions are more
   powerful then Sextiles. 3) Finally the orb of the aspect, i.e. exact
   aspects are more powerful than wide ones. (The influence of the orb
   varies linearly from max power at exact to zero power at the limit of
   the orb - sorry Maggie M. and Mark K. - no complex aspect wave
   functions, at least for this version :)

   Special thanks goes to Mark K. who initially presented this idea of
   interpreting overall influences to me. I basically just took his
   ideas, polished them a bit, and put it into the code. Interestingly,
   while programming this feature, I had a dream about him, in which he
   elaborated upon some of the ideas and even gave me suggestions for
   some of the planets' default power values (astral visitation?) And,
   while on the subject, I've had a couple of other Astrolog dreams; I
   had one neat one while working on the -h extension (described later)
   about a far distant future version of Astrolog that could actually
   teleport one to the places which they cast charts for :)

C) -v switch: This isn't really a new feature, but rather a formal
   specification for the standard chart listing of the planetary
   positions. Before, one would get this chart by default if they didn't
   specify any other chart types, and they would get it along with
   everything else in the -e option, but there was never any formal
   switch for it. In other words, before there was no way to, for
   example, display the standard chart, followed by an aspect grid, since
   there was no switch to choose the standard chart. Now, one can specify
   "-v -g" and get the above mentioned combination.

D) -v addition: The standard chart listing of the planetary positions
   has been expanded to include an extra field for the "velocity" of each
   planet. This velocity value approximates how fast the planet is moving
   through the zodiac with respect to the Earth (or whatever the central
   body is set to) in degrees per day. This value of course, goes
   negative when a planet goes retrograde. This is useful not only to get
   a feel for how fast each planet moves through the zodiac, but to
   determine when a planet is about to go retrograde or direct - the
   value approaches zero when the planet changes direction.

E) -v0 switch: This switch is just like -v except that it modifies the
   planet velocities slightly. Normally, it isn't a trivial task to
   determine precisely when a planet is going to change direction. This
   is because, for example, although a velocity of 0.010 degrees/day for
   fast moving Mercury means it's about to turn retrograde, the same
   velocity value is normal for slow moving Pluto. The -v0 switch divides
   the normal velocity values by how fast each planet moves with respect
   to the Sun, meaning that all planets will now have an average
   *relative* velocity value of 1.000, and in all cases, a velocity of
   2.000 means the planet is moving twice as fast as normal, and one of
   0.010 means the planet is about to turn retrograde.

F) -d addition: The -d aspect search routine has been expanded to
   calculate and display the times when a planet changes direction.
   Before, in such a listing, it would be shown whenever a planet changed
   direction during a day, but the exact time of the station wouldn't be
   printed for it.

G) -U switch: Astrolog 2.20 has the ability to display the positions
   of 46 of the brightest and most important stars in the sky. To include
   these stars in a chart, use the -U "universe" option. The 43 brightest
   stars, i.e. all those with apparent magnitude values < 2.0 are
   included, in addition to three dimmer stars which are considered
   significant, i.e.: Polaris the North star, the Pleiades star cluster
   (home of our extraterrestrial cousins), and Zeta Reticuli (home of the
   Grey aliens.) One bright star is called "Orion", which is formally
   Alnilam, the middle star of Orion's belt. Since stars are fixed in
   the sky, they will never change position in the -s siderial zodiac,
   although they will slowly precess forward in the normal tropical
   zodiac. The -R restriction option can be used to determine which stars
   are actually included, although the -U option needs to be included to
   get any stars at all. In X windows, the stars are denoted by three
   letter abbreviations (as are the uranians and minor house cusps), and
   are colored according to their brightness: yellow for stars brighter
   than (less than) magnitude 0.0, gold for dimmer ones from 0.0 to 1.0,
   orange for those from 1.0 to 2.0, and finally the dimmest special
   stars with a magnitude greater than 2.0 are red.

   In the -v standard chart, -Z horizon chart, and in the -O object list,
   where all the stars are printed sequentially, it can sometimes be
   confusing to locate the star you want among 42 others. The -U option
   can be modified to sort the stars in various ways. If one uses -Ub
   instead of just -U, the stars will be listed in order from brightest
   to dimmest. Doing -Un instead of -U will alphabetize the stars by
   name. -Ul will sort them by their altitude from highest in the sky to
   lowest, while -Uz will sort them by their zodiac position. Note that
   any star ordering will have no visible effect in X windows, and one
   must still use the default ordering when passing numbers to the -R
   option to restrict various stars.

H) -C switch: This new option must be indicated to include the four
   minor house cusps (i.e. 11th, 12th, 2nd, 3rd) in the various chart
   options, such as the -g aspect grids, -T transit searches, the X wheel
   chart, etc. This option of course won't have any effect on certain
   charts where only physical bodies are shown (e.g. -Z, -S, -L) or where
   all house cusps are already indicated in the chart (e.g. -v, -w).

I) -O0 switch: The old -O switch simply displays a list of all the
   objects, cusps, uranians, and stars, along with their index numbers.
   This list can be affected by the -R restrictions, and the -C, -u, and
   -U switches must be included in order for all of Astrolog's objects to
   get listed. In order to make it easier to simply display a list of all
   78 objects Astrolog recognizes, the new -O0 option is just like -O
   (and is equivalent to "-C -u -U -O") except that it will ignore all
   restrictions and always list every object. Stars are printed in the
   list along with their azimuth, altitude, and brightness values.
   (Remember that when -O is encountered, it immediately executes and
   terminates the program, so any modifying switches must be before it.)

J) -RC, -Ru, -RU switches: These three switches are similar to the -R0
   option in that they initially restrict objects, i.e. all the minor
   cusps, Uranians, and stars, respectively from appearing. For example,
   if you want to include only the star Sirius in an X window chart
   without having to also include all the other stars (or having to enter
   a very long restriction list), do: "astrolog -U -RU 48 -X", which will
   include the stars, and then restrict them all except Sirius, before
   making the chart.

K) -h <arg> expansion: The -h switch which allowed heliocentric charts
   to be computed has been expanded to allow charts to be cast with any
   planet as the center. The option takes a parameter to indicate which
   object to center the chart on, e.g. do -h 5 to cast a Mars centered
   chart. (Moon centered charts are not allowed.) As before, -h by itself
   means to do a heliocentric chart.

L) -rm <file1> <file2> switch: Time-space midpoint relationship charts
   are now supported. Doing "-rm chart1 chart2" will calculate the time
   and location exactly half way between the times and locations as
   indicated in the two files. Unlike all other types of relationship
   charts, this one actually exists in space and time, and therefore can
   be treated like a single chart and can be output with the -o option.

M) -r0 <file1> <file2> switch: A distinction has now been made between
   synastry relationship charts and the actual comparison between two
   separate charts. The -r0 option must be used to generate these
   comparison charts, e.g. the aspect grid between the planets of two
   charts (and the new X chart described later). The -r0 option will act
   like the -r synastry option in certain displays that can't compare two
   charts; for example, "-r chart1 chart2 -g" and "-r0 chart1 chart2 -g"
   are different, because one generates the aspect grid within a synastry
   chart, and the other an aspect grid between all the planets in the two
   charts, but "-r chart1 chart2 -v" and "-r0 chart1 chart2 -v" will do
   the same thing. (Note: the "-t file" current transit option is
   basically a shorthand way of doing "-r0 file now".)

N) -G switch: This switch generates a special type of locational
   analysis chart, called a geodetic chart, in which the house cusps are
   computed from a different source, i.e. as a function of only the
   longitude and latitude. This basically gives every spot on the planet
   a different unique set of house cusps, and can be used to analyze the
   characteristics of different areas, and their influence on you if you
   insert your own planets in the houses. This type of chart was
   described in the January 1992 issue of Dell Horoscope magazine, from
   which I learned how to generate these charts. Basically, the Midheaven
   is approximately the longitude value converted from degrees into the
   appropriate zodiac sign; for example 0 degrees E goes to 0 degrees
   Aries, 30 degrees E goes to 0 degrees Taurus, etc.

O) -L <arg> addition: For text screens, one can pass an optional
   parameter to the -L or -L0 astro-graph option to give the latitude
   step rate at which the Ascendant and Descendant lines are computed.
   This value is by default 5 degrees, although one can may increase or
   decrease it to any integer (subject to the restriction that the number
   160 is divisible by it.)

P) -g0 addition: A new planetary configuration has been added to this
   option. In addition to flagging the Grand Trines, T-Squares, and so
   on, any chart Stellium's are located. In a Stellium, three objects
   must all be conjunct with each other.

Q) -ga switch: Ability to determine whether an aspect is applying or
   separating (is about to happen or just happened) has been added to the
   -g option. Normally the aspect orbs are flagged as being + or - based
   on whether they are greater or less than the proper amount (e.g. a 91
   degree Square has a +1 degree orb while a 89 degree one a -1 orb.) If
   one, however, invokes the -g option as -ga instead, a negative orb
   will indicate an applying aspect while a positive orb a separating
   one. (To estimate applying vs. separating, the program examines the
   planetary positions and their velocities at the time in question.)

R) -g0 expansion: For relationship aspect grids, the -g0 option will
   display a midpoint grid instead of an aspect grid between the planets
   in the two charts e.g. "-r0 chart1 chart2 -g0". Before, the -g0 switch
   with comparison charts wouldn't behave any different from just -g.

S) -s0 switch: For astronomers out there, the new -s0 option will
   print all planetary positions in the right ascension hours/minutes
   format instead of the sign/degrees/minutes astrologers are accustomed
   to. This will affect how the objects are listed in the -v display, and
   how the star azimuths are displayed in the -O list. For example, 0
   degrees Aries is represented as 0 hr, 0 min; 0 Cancer goes to 6 hr, 0
   min, and so on through the 24 hour clock.

T) -p0 <arg> switch: User definable progression rates can be specified
   with this new option. When using the -p progression option, Astrolog
   assumes you want the standard "year for a day" rate of secondary
   progressions. By passing different values to the -p0 switch, one can
   change the default "365.25 days for a day" to any value they want for
   some less often used method of progression. For example, one can do
   "-p0 7 -pn" to do a week for a day, "-p0 -365.25 -pn" to get negative
   year for day progressions, and so on. (Note that "-p0 1" would be the
   same as if no progression were done at all.)

U) -z expansion: Normally the -z option takes an argument which will
   then become the default time zone. If one, however, invokes it by
   itself, it will subtract one hour from whatever the default time zone
   presently is. This is useful since it is equivalent to adjusting any
   times printed to Daylight time, i.e. it will add one hour to any times
   displayed. (When entering the birth time for charts, one is supposed
   to subtract one hour if Daylight time was in effect; note that
   subtracting one hour from the time zone will do the same thing.) For
   example, over here on the West Coast, I have my default time zone
   compiled to be "8"; now that Daylight time is in effect here, I can do
   -z 7 or just -z to decrease the default time zone when I make a -T
   transit list, which will in effect add one hour to the local times
   displayed, or in effect "Spring ahead" the clock for me. (For a better
   way of adjusting Astrolog for Daylight time without having to specify
   -z all the time, recompile the program, or add one hour to the times
   in your head, use the "defaults" file described later to change the
   time zone.) Remember that the -z (and -l) switches must be before any
   other switches they modify (such as -n) in order for the new default
   to take effect.

V) -- <arg> switch: This new "dash minus" option is just like the old
   "dash plus" (-+) option that's already in place, except it subtracts
   instead of adds the specified number of days from any chart cast. This
   is only for convenience, in that "-- 1" is the same as "-+ -1".

W) -w expansion: Chart header information has been added to the -w
   text wheel chart option. Before, the space in the middle of the chart
   was left blank, but now displayed in it is the same header info as is
   at the top of the standard -v chart.

X) There are now wider orbs allowed for the Sun and Moon in the aspect
   grids. Normally, only the aspect in question determines the allowed
   orb, but the Sun and Moon will now each add 1 degree to whatever the
   orb would have been. (This excludes minor objects such as the North
   Node, Part of Fortune, Vertex, and all the stars, for which the orbs
   are not allowed to ever exceed two degrees.)

Y) When specifying command switches, the leading dashes are optional,
   and aren't necessary any more. For example, the command "astrolog -i
   chartfile -R -u -U -Z -Xs 300 -Xi -XB" can be abbreviated as "astrolog
   i chartfile R u U Z Xs 300 Xi XB". (This is subject to a couple of
   minor limitations, in that one can't have the -1 or -3 option follow a
   -R restriction list of numbers, for obvious reasons.)

----

Astrolog 2.20 includes the ability to search an input file for various
default parameters to use in the program. This allows one to easily
change major defaults without having to recompile the program, which
is useful if, say, one receives a compiled executable from a friend
who had a different configuration. The program looks for the file
"astrolog.dat" in the current directory, and if not there, looks for
it in the default directory. Parameters in this file will override any
defaults compiled into the program, although the highest priority is
still given to the command line options. Note one doesn't *have* to
have this file in order to run the program - if not found Astrolog
will still run as before. Presently, the parameters one can change in
this file are: default time zone (as indicated with -z option),
default longitude and latitude (as in -l option), number of aspects
(-A option), default house system to use (values as in -c option).
Then come default restriction values (as with -R option) for the first
20 objects (0 = active, 1 = restricted). Next are the orbs (as with
-Ao option) for the 18 aspects. Finally, comes a long list of the
influence values used by the -I option, i.e. the power values of each
of the first 20 planet objects, of the 12 houses, and of the 18
aspects. The only major thing that one *can't* change in the file is
the default directory path in which the program looks in for input
files if not in the current directory, since Astrolog needs the
default directory in order to be able to locate the file in the first
place! The "astrolog.dat" file included with this version of the
program has some "comment lines" describing what is contained in each
line. One can chance or delete comments as long as they make sure that
an equals sign ('=') immediately proceeds any value or list of values,
since the program uses this character to determine where comments end.

----

Additional new features and extensions follow below; however, these
only affect the graphics portions of the program, and therefore only
come into play if the X11 compile time option is set.

A) True relationship wheel charts can now be displayed in a window,
   i.e. where the planets of both charts are displayed in separate rings
   of the same wheel. Use the -r0 option to display this comparison type.
   For example, for the command "astrolog -r0 person1 person2 -X", the
   following is displayed: The signs and houses as in person1's chart are
   drawn in the outermost part of the wheel. Inside this is a ring of
   person2's planets as displayed in person1's houses, and inside of this
   are person1's own planets. Finally at the very middle is an aspect
   grid, which shows those aspects that are occurring between the objects
   in the two charts. Basically this is just the standard wheel chart for
   person1, except that person2's planets are in an outer ring of objects
   and the aspect grid shows the aspects of the relationship. Putting
   such a chart in animation mode only affects person2's planets, so this
   is a great way to analyze transits: Doing "astrolog -t yourchartfile
   -X" will show all your current transits, and allow you to easily
   animate the transiting planets through your natal signs and houses.

B) More color: For color X terminals, the -XG globe display and -XW
   world map display are now done with the continents in different
   colors! This makes them look much better than before. Each of the
   seven continents is in a different color of the rainbow, and the
   colors are chosen to correspond to the appropriate chakra (etheric
   energy vortex along the human spine) that goes with each land mass.
   They are: Africa - red - Root chakra, Australia - orange - Navel
   chakra, South America - yellow - Solar plexus chakra, North America -
   green - Heart chakra, Europe - blue - Throat chakra, Asia - indigo -
   Third Eye chakra, Antarctica - violet - Crown chakra. Major lakes are,
   of course, colored navy blue.

C) Mouse buttons: Pressing the mouse buttons in the X windows will now
   do various functions. The left mouse button acts as a pen that allows
   one to actually draw on the chart: press it and drag the pointer to
   draw a line on the window - good for aiding in analysis or in
   presentations. (Any scribbles one makes will disappear the next time
   the chart window is updated, therefore drawing will have little effect
   when in animation mode.) The middle mouse button will only work when
   the world map is shown, i.e. in the -L astrograph or -XW world map
   displays: press it and get the approximate longitude and latitude of
   the place on the map where the pointer is. For the three scale sizes
   of 100, 200, and 300 percent, the accuracy is to the nearest degree,
   30', and 20', respectively. So, if you want to cast a chart for
   southern Madagascar, Africa, but don't know the coordinates, click the
   middle button on the map for a good approximation! Finally, the right
   button acts just like the 'q' key, and will terminate the window.

D) '[', ']' keys: Not only can the globe display be rotated, but the
   poles can be now tilted down at various angles! (This basically makes
   the -XP polar globe view option obsolete; it's still in there only for
   backwards compatibility.) Press the '[' and ']' keys when the globe is
   being displayed to respectively "pull down" and "push back up" the
   angle of the polar axis from which the globe is viewed.  Combining
   this with the globe rotation allows one to move any point of the globe
   to the center of the screen.

E) 'l' key: Press the 'l' key in a window to inhibit the labeling of
   all planets in the various charts. Instead of drawing the little point
   and then the glyph near it, just the point is displayed. This mode is
   mainly useful for the -Z horizon and -S space charts (and has little
   use for anything else) when in cramped quarters or to get a more
   realistic view of how the sky actually looks.

F) -XT switch: In addition to the 'T' key which will toggle off or on
   whether the chart parameters are displayed at the bottom of the
   window, the new -XT option will do the same thing, giving control of
   the feature when a formal window isn't actually opened, e.g. when
   displaying to the root.

G) 'O', 'o' keys: Have you ever animated your natal or some other
   chart to some far distant future or past time, only then to wish you
   could somehow easily get back to the original chart? You can now, by
   pressing the 'O' key in a window, which will recall to the screen
   previously "saved" chart parameters (which are by default set to
   whatever you started the window with.) Press the 'o' key to change
   this default stored chart to be the chart that is presently in the
   window.

H) 'B' key: Press the 'B' key in an X window to dump whatever is
   currently being displayed to the background root window. This is
   basically the corresponding keypress to the old -XB option.

I) 'C', 'u', 'U' keys: Pressing the 'C', 'u', and 'U' keys in the
   window will toggle the restriction status of the four minor house
   cusps, the uranian planets, and the fixed stars, respectively. These
   keys compliment the old 'R' key option already in place, and are the
   counterparts to the -C, -u, -U, and -RC, -Ru, -RU options.

J) 's', 'h' keys: Press the 's' key in the window to toggle whether or
   not the siderial vs. tropical zodiac is used. Press the 'h' key to
   toggle to a heliocentric based chart or back again to a geocentric
   one. These of course correspond the the -s and -h options.

K) 'v' key: Press this key to dump back to the text screen the list of
   where all the planets currently being displayed in the window are.
   This display is the same as produced with the -v switch, and is useful
   if one wants text to indicate where everything in the chart is.

L) -Xi switch, 'i' key: Certain people have asked that some of the X
   charts be modified in various minor ways, i.e. in either adding or
   removing certain information. Rather than add a new hard to remember
   minor option for each change, I have added one major new switch which
   covers all the charts. The new -Xi switch will invoke this
   "induce/inhibit information" option, and pressing the 'i' key in a
   window will accomplish the same thing by toggling the mode's status.
   By default, all the charts are as before, but when this bonus option
   is set, it affects each X window chart in a different way, as follows:

 o For the standard -v and relationship -r0 -v wheel charts, it will
   inhibit the display of the aspect grid in the center - useful for
   speed or when doing large time lapse animations when it would get in
   the way.

 o For the -g aspect grid, it will flip the aspects and midpoints across
   the center diagonal, i.e. the midpoints will be below it and the
   aspects above it, instead of the other way around. For the -r0 -g
   relationship aspect grid, the entire grid will be replaced with one
   showing all midpoints between all the objects in the two charts.

 o For the -Z horizon chart and -S space chart, it will, for the major
   planets, increase the size of the "points" showing where each object
   actually is, making a brighter "spot", for easier viewing; combine
   this in the horizon chart with the 'l' key label inhibitor and get a
   very realistic view of the night sky, with planets brighter and all.

 o For the -L astro-graph chart, this will eliminate the display of the
   Ascendant, Descendant, and Nadir lines, leaving just the vertical
   Midheaven lines and zenith points, for a remarkable increase in speed
   and much less clutter when including many objects.

 o For the -XW world map display, this will show the Earth's ley line
   locations; and for the -XP polar globe view, it will show the southern
   hemisphere instead of the northern.

 o For the -XG globe display, it will display the zenith locations of all
   planets (and stars if -U in effect) on the globe, i.e. where on the
   Earth each object could be viewed by looking straight up. This on the
   globe display is almost identical to the astro-graph chart without its
   various lines, except of course that the projection of the world map
   is different. It's also similar to the -Z horizon display, except that
   it's free from the distortion of projecting the celestial sphere upon
   a plane, so it has use to star gazers. However, animation mode here
   will still only affect what part of the Earth is viewable, and won't
   update the chart from which the zenith locations were obtained.

----

Here is a list of bug fixes over version 2.10:

1) There was a major glitch in the uranian overwrite routine which
   would not only display the uranian positions a degree or two off from
   where they should be, but would also garble the positions of all the
   other objects, too! Since the uranians are now displayed separately,
   this is no longer a problem.

2) The display of midpoints was always 0.5 degree ahead of where they
   should be. For example, the midpoint of planets at 0Gem and 0Can would
   have been 15Gem30 instead of 15Gem0. Believe it or not, this bug has
   been in Astrolog since version 1.1, and I'm glad to say that it's
   *not* in version 2.2!

3) If one switched X window modes from a wheel chart to the
   relationship aspect grid, extra junk would be displayed in some cells.
   The aspect grid routine has been fixed now to make sure that those
   cells that don't have aspects in them stay blank.

4) Attempting to display a chart with no time or space (i.e. a chart
   generated with the -o0 option) in an X window would dump core if the
   chart information was also to be printed at the bottom of the window.
   Now, these charts are no longer a problem, and as with the standard
   listing, these charts are flagged as existing outside the space time
   continuum.

5) The -Z local horizon chart when displayed in an X window would fail
   to recognize the -R restrictions before, and they properly do now.

6) Certain VMS X window systems didn't like the procedure I named
   "box" in the graphics portion (was already defined). This has been
   renamed to eliminate the problem.

7) When downloading the Astrolog source code, certain systems didn't
   correctly transfer lines that began with a decimal point (e.g. the
   numbers in the planetary data area). These have been prefixed with 0's
   to fix the problem.

8) Even when compiling for non X window systems, the previous version
   would still compile in the graphics draw tables and world map data.
   Although this wouldn't affect the running any, it would needlessly
   make the executable larger. Now, trust that the only data compiled
   into the program will be what the user wants as expressed in the
   compile time options.

9) The X window response time was very slow if the world map was ever
   displayed in the lowest scale size, due to continuous error processing
   since the vertical axis of these maps were smaller than the
   established minimum window size. The minimum window size allowed has
   been adjusted to accomodate all scale sizes. Also, on a related note,
   Astrolog windows behave better when one resizes them: instead of
   immediately resizing the window to within bounds if one makes the
   window too big or small, it now won't allow windows to be stretched
   beyond the established limits.

0) Finally a warning for PC users: You will probably want to change
   the value of DIVISIONS in astrolog.h from its current value of 24 to a
   lower value like 6 or so. Leaving it as is invoked complaints of
   extreme slowness and occasional multiple hits in the -d aspect search
   routine, where the same aspect would get listed more than once. Also
   for PC users, I eliminated the problem of the 16 bit PC ints not
   having enough precision to compare with the 32 bit Unix ints, in that
   everything is done using longs now.

Astrolog 2.25 posted Thu, 18 Jun 92 18:54:43 GMT
************************************************

After posting version 2.20 to alt.astrology, I found one small bug and
a few omissions, so I simply made those changes before posting
Astrolog 2.25 to comp.sources.misc. To be honest, I did add one small
feature or two, but nothing major.

Anyway, here is a list of the changes I made in version 2.25:

1) Bug fix: Version 2.20 has a bug which I accidentally introduced, in
which the planet declination values in the standard -v chart listing
would always be positive. Version 2.25 fixes this. (This is basically
the only change that will affect non X windows users.)

2) Omission: When pressing the 'H' key in an X window to get a list of
valid keypresses, version 2.20 wouldn't display all the keys
available, since I forgot to include some of them in that help list.
The key press features that I forgot to include, which are now
properly listed in 2.25, were: The 'h' heliocentric toggle, the 's'
siderial zodiac toggle, the 'B' dump window to root background key,
and the 'v' dump chart positions to text screen key.

3) Omission: Related to the above, I forgot to include the new -ga
applying vs. separating aspect grid switch in the -H help list. (It
would still work correctly, it just wasn't listed.)

4) New features: In X windows, press the 'f' key to toggle the status
of whether or not the chart should be modified to correspond to the
appropriate domal chart (where the house positions are represented as
zodiac positions and vice versa). Press the 'F' key to toggle the
status of whether or not the chart should be modified to correspond to
a decan chart (where each sign is divided in thirds representing the
two other signs in its element). These keys of course correspond the
-f, and -3 options, respectively.

5) Enhancement: The -XP polar globe view feature can now be animated.
Before, entering animation mode with such a view in place would yield
no visible effect. Now, such a chart will rotate about pole in the
center of the screen.

6) I probably should have made this more clear in the version 2.20
"Update" file before, but when compiling, be sure to change the values
in the "astrolog.dat" file, in addition to the "astrolog.h" file, to
correspond to your present location. The documentation now makes this
more clear, and includes one large "Helpfile" listing all of the
features and documentation in this version of Astrolog. (Remember when
posting version 2.20 here, I just included a list of changes added to
version 2.10; the new Helpfile is a large stand alone documentation.)

7) Finally, I should mention that my e-mail address has changed. It is
no longer pullen@lynx.cs.washington.edu, and this change has been made
to the code and documentation of version 2.25.
