You have to take the foot off; the reset hole is underneath. It's one of the top holes, but I don't remember which (it has a small "R" next to it)

I just uploaded my simplex library v1.1 (the first public release) to

Find attached the rdm.

Simplex Library v1.1                               1-28-93
README File
**************************************************************************

Well I finally did it.  I rewrote Ricardo Marimon's simplex procedure
entirely in sysRPL and made it into a library.  It now stores all temporary
variables as a Library Data object in a variable called LPdat in
the current directory.   This makes the program a little more idiot proof
since you cannot alter the problem directly.

The library itself bytes out (on the HP) at 15800.5 with a checksum of # D7DCh
and uses lid # 517h (1303d).  I created the .asc file with tasc
on my sun and have not tested if it extracts properly.

Currently it only implements the 2 phase method to find an initial
feasible solution, but a primal-dual method is on the drawing board.

The user accessible functions do quite a bit of error checking, but I
cannot guarantee that this library will not cause memory loss.
I will graciously accept any and all bug reports and suggestions.
Also, I will maintain a list of 'registered users' to whom
I'll automatically send updated libraries.  Just send me a note
including your email address.

I do graciously thank Ricardo for doing all the hard work on the
matrix manipulation and the original logic of the program.  Also
the .doc file is almost entirely verbatim from his original posting.

Actually over here (and many other countries as well) we only have trial by
judge, not by jury. A jury is more likely to disbelieve the cheaters if they
say they didn't cheat regardless if they did or did not cheat. So the jury is
unlawfully biased against the cheaters. In a trial by judge the judge is
impartial (well in theory). He has no choice but to presume that the cheaters
are innocent (although he knows they are guilty as hell).

I need some help with a short (I hope) routine.  Is there a way to convert
a string to a name?  Using OBJ-> works sometimes, but if there is a
variable with that name already assigned you get the value of the
variable, not the name itself.

Example: type "a" OBJ-> you get 'a'
         type 3 'a' STO "a" OBJ-> you get 3

I want to get 'a' every time.  Can someone help?

   One advantage of the 48 is that its ROM routines would be the 
   C library/kernal, so code needn't be that big.

Every so often, someone thinks of the idea of writing a C
compiler for the HP 48.  I think it's not worth the effort, for
several reasons.

The Saturn is not a processor that would be easy to write a code
generator for.  Register usage is non-orthogonal.  There are lots
of register fields, few of which correspond well to traditional C
data types.  The hardware stack is limited to 8 20-bit values, so
a parameter-passing stack would have to be implemented in
software.  As a consequence, it would be difficult for a C
compiler to generate efficient Saturn code, and typical C
programs wouldn't be easily portable to the Saturn architecture.

The ROMs don't have that many routines that correspond to
standard C library routines.  You'd still have to write a C
runtime library, a task complicated by the need for an HP 48 C
system to interface with the normal RPL environment.

Perhaps the biggest problem with any C development environment
for the HP 48 is that it would be at odds with the fundamentally
interactive nature of the HP 48.  C is a reasonably good language
for developing larger applications, but it is also difficult,
arcane, and not designed for interactive, incremental program
development.  C has its place, but not on the HP 48.  System RPL
is by necessity the systems programming language of the HP 48,
and Saturn assembler the language of choice for the low-level and
time-critical applications.  You could write a C-like compiler
for the HP 48, but I do't think you could really implement ANSI C
well on its architecture.

Just because a machine can be programmed in assembly language
doesn't mean that it can or should have a C compiler.  C is not
the be-all and end-all of programming languages, and any serious
programmer should be able to work in a variety of languages.

It would be cool to see a Scheme interpreter/compiler for the
HP 48, though. :-)

	Voltage has a small consideration since this is what disrupts
your nervouse system, but current is the main consideration.  The
shockers some people carry have a high voltage ( 120,000 & > ), but they
are only powered by a nine volt battery so the current is very low.  And
a 1.5 volt battery is enough to stop your heart if the resistance is low
enough ( I've been told bridgeing it between open cuts on the thumbs could
give a low enough resistance).  Remeber that voltage=current*resistance.
These must equal out.
	Well, thats my 2 cents worth.

Embed your code in a IFERR structure.  Pressing ATTN will then be
treated as an error, and it'll be trapped so that you can handle it
however you wish, including (although not recommended) jumping right
back into the IFERR structure.

The built-in IFERR can be broken out of by repeated presses of the
ATTN key.  So Bill Wickes wrote a beefier version of IFERR and posted
it as a library two years ago.  It's available as IFERR.LIB on Goodies
Disk #3, and no doubt at seq.uncwil.edu also.  This library makes the
IFERR structure bulletproof.

In Europe *that* works: no guns allowed. But to the banning of HPs: what's the
alternative? It is an extremely easy way to cheat. Over here in Europe those
HPs are costly, so not very many students own one. So now you can take
primitive actions like seperating these people during exams. But if a large
minority would own one, we're in trouble.

Sure, hang 'm high! But...

Do you know that if those students would sue you, they have an excellent case?
I guess in the States you only have one proctor during an exam. The word of
one man against another doesn't work in court. Even worse, since you accuse
him of cheating, you'll have to supply the evidence. If not, well, how much
money can you get from a slander law suit?

Of course, the students will never graduate (thesis on "mission impossible"),
but, heck, they don't have to with your money :-(.

Over here in the Netherlands the students wouldn't get much money, but for
them it is much easier to go to court and sue me. Fairy-tales? No, several
professors have been sued in here with succes (albeit not on cheating, but on
other minor irregularities). About a year ago a student sued a famous
professor that gave him an F (well, we use numerals over here). The judge
ordered the professor to give him a C, if not, he had to pay about $5000 a
day.

Luckily for us most cheaters reluctantly undergo their punishment, but some
day ... (I hope I'm not the one that is sued).
