From the mail_bsd(1) man page:

Under commands:

     folder      (fo) The folder command switches to a new mail file or
                 folder. With no arguments, it tells you which file you are
                 currently reading.  If you give it an argument, it will write
                 out changes (such as deletions) you have made in the current
                 file and read in the new file. Some special conventions are
                 recognized for the name.  @ means the current file in read-
                 only mode, $ means the current file, in read/write mode if
                 possible, # means the previous file, % means your system
                 mailbox, %user means user's system mailbox, & means your
                 ~/mbox file, and +folder means a file in your folder
				  ^^^^^^^
                 directory.

                 Issuing the command ``folder %'' while you are reading your
                 system mailbox is a convenient way to incorporate new mail
                 which has arrived during the session.


Under options:

     folder      The name of the directory to use for storing folders of
                 messages. If this name begins with a `/', Mail considers it
                 to be an absolute pathname; otherwise, the folder directory
                 is found relative to your home directory.


In english...

If you want to save mail in the directory ~/Mailbox, add the following
to your ~/.mailrc file:

	set folder=Mailbox

Now you can save as follows:

	s +test

and the current message will be saved to the file ~/Mailbox/test

The man page could be quite a bit clearer on this issue.  I'll have to
rewrite it (again) one of these days.  Thanks for pointing it out.

To add one more bit, and be quite precise, I have personally
heard the following, (my paraphrase, not a direct quote, but definitely
the intent of what was said),
directly from Microsoft people, in public:

1) NT actually works on both R3000s and R4000s.
2) The CDROM has the R4000 version on it.  IF an R3000 market
would develop, we would support it.  However, as it stands,
we don't really expect that to happen, given that right now,
vendors building MIPS ARC-compliant machines are interested
in R4000s, and by the time this all gets into more-than-
developer volume, R4000s and R4000 derivatives will be
cheap enough anyway.

So, anyway, I think it is clear: if some compelling reason
happens to make them support R3000-based products (as opposed to
just happening to have that running), they'll do it,
but don't expect so right now.

Hello...

I am using X and GL at the same time.  I want to have one event loop for
both my X interface and the GL window.

Is there a way to grab X events that occur on a GL window?  That looks like
the best way so far, but I can't tell how to treat the GL graphics window
as an X entity.

The very "hacky" way would be to rewrite XtMainLoop() so that it interleaves
and dispatches events from both queues, but I really hope there is a better
way..

The instructions are quite clear.  It is called 'installing software'
(well, > 95% of it is).  The Installation Guide is quite clear on all
of that.  That process will make filesystems if required, so you
don't need to worry about that much.

The only other piece of info that you need is that fx will create
the partition layout.  In fact, by default fx will do almost all
of the initialization you need when it notices that the disk doesn't
yet have a volume header on it.  The only other thing you would have
to do is to change the partition tables if you don't like the default
(the top level repartition menu makes this easy).

The Installation Guide even contains instructions on how to boot
the standalone fx from the various types of installation media,
and how to determine which fx to boot (there are several different
versions, depending on your hardware type).

If after reading the Installation Guide, something still isn't clear,
please let me know.  I spent a lot of time working with the author
if the I.G. to make it very straightforward and simple.

I read in my documentation for zip that tab stops can be set at values

the tab size, it still uses 8 character tabs, but will use spaces to
"fake" a different tab size.

I have files that get edited on other machines in addition to the sgi and
I use a tab size of 4.  However, no matter what I put in .ziprc, these

Is this correct? Is there anyway around this?

Is there an option that says "whenever I hit the tab key, insert spaces
to pad to the next tab stop"?

There is actually a sentence some place in the install manual that
tells you how to do this.  (here I go, flaming the IRIX manuals again)
There is a command you need to load to initialize the hard drive and make
it ready for loading of the OS.
Ie the disk has to have a header written containing the partition
sizes/bad blocks etc.
I remember it took me a while to get it to work.
Ie getting all the parametters right for my drive id etc.

Just keep reading the install manual all the way through you will find it.
I remember it took me 3-4 hours of hair pulling before
I found it and then..  Trying to figure out how to use it.


Another comment to SGI here.
PLEASE put in the index
HOW TO INITALISE A NEW HARD DISK chapter
Make sure you put instructions on how to use the Disk initialise program.


Also, another problem I had is that I made 4 partitions when I init the disk.
/
/usr
/home
/tmp
plus a swap.
on a 1gig WREN VII

Then when I started to load the OS, the bloody inst program would ONLY
see and load the OS on to a set partitions.  THE WRONG PARTITIONS.
The only way around this was to make the partitons it wanted to
use as / and /usr (mainly where it chose /usr) was to run the disk
init program again and change the partition table to what it liked.
BLOODY ANNOYING.

Also, the other /home and /tmp partitions.
I had to make the devices BY HAND.  I suppose thats no big deal but
it took me a long while to figure out how IRIX did its devices.
What about a MAKEDEV script or similar????

Thank god I have a little experience with this stuff.  Otherwise
I wouldn't have a hope...  All I can say is poor
average Joh Blow who has not a clue.


Flame off.

Sorry about this but this message brought it all back.

You cannot really lump Alpha Blending and Anti-Aliasing into one class of operations here. RealityEngine does indeed perform anti-aliasing differently from the VGX/VGXT class of machines.  On the VGX/VGXT, anti-aliasing was performed on the fly as vectors, points and polygons were rendered, impacting multiple pixels downstream in the frame buffer for each pixel being rendered.  This allowed the VGX/VGXT to smooth out the points and edges using a weighting function around the primary pixel.

On RealityEngine, anti-aliasing is performed farther downstream in the graphics pipeline.  When the system determines the coverage of a pixel by a vector point or polygon, it does so by checking the coverage for each of a number of sub-samples within that pixel. There is sufficient memory in the RealityEngine frame buffer to support up to 16 sub-samples per pixel, including a sub-sampled Z value to insure that false edges created through z-buffering are properly anti-aliased.

Just like the VGX/VGXT, the RealityEngine maintains positional accuracy of vertices down to an 8x8 subpixel grid, or 64 subpixels/pixel. On the VGX, this is used to determine how to weight the rendering of multiple pixels for each pixel drawn to perform anti-aliasing.  On RealityEngine, however, from 0-16 of those subpixel locations are designated as sample points. The system then determines not the coverage of the pixel, but of each of the multiple sub-pixel sample points.

The number of covered sub-samples determines the rendering weight of the primitive (point, vector, poly) being rendered (i.e. if 6 of 8 samples are covered, the pixel would be blended with 75% of the color of the primitive).  There is virtually no performance impact when performing this type of anti-aliaing on the RealityEngine, while the older style anti-aliasing resulted in a 2-to-1 performance hit on a VGX/VGXT machine.

Alpha Blending is much the same on RealityEngine as for the VGX/VGXT except that computations are performed at a sub-pixel rather than a pixel level. Sorting still helps.

We use programs developed on VMS which have large help libraries to go with them

Some program which uses the embeded level numbers in the text file etc would be very

Hi,

I'm trying to make some of the my libraries into shared libraries since the
executables they produce are getting a little too large for comfort.  After
fighting through "man 1 mkshlib" I got a small example library to work BUT :

a) I can't the shared library to access routines outside itself (e.g. printf
etc).  When I run mkshlib with -v I see the 'ld' that causes this.  Is there 
any way round this since lots of the libraries access further libraries and 
functions.

b) I'm a little concerned about choosing memory addresses out of mid-air for
the shared library.  I've read the NOTES section and obeyed but I wondered if
anybody had practical advice/horror stories to give on the subject.

c) Is what I'm trying to do sensible.  Are IRIX shared libraries designed for
this?

Thanks in advance for any hints/suggestions/abuse
