ATTENTION - Ticalc.org / TI-Philes Archivers - please do not add this file
to your archives yet! it is very buggy and not even worthy of a version
number.  a working version will be available soon, so add it then. thank
you.

okay now that we got that over with... this is my humble shell-like program.
it fixes some problems (IMHO) with TI's programs menu. IMPORTANT! before you
begin, backup everything on your calculator! also remember that i am not
responsible for any loss resulting from you using this product!

load this program into your calculator and run it with "Asm(Kshell" (do NOT
run it from a shell!!! it might work but don't take chances). as soon as the
program finishes (it clears the screen) turn the calculator off and back on
again. now push PRGM and you should see a new patched menu with the
following options - "BASIC", "ASM", and "EDIT". the BASIC menu contains only
BASIC programs and the ASM programs. the EDIT menu is the same for now.

Here's the most likely bugs: first, it probably won't work on ROM version
1.3 (but it might). second, even after turning the calc off and back on, it
might do something weird. i don't even know why the calc has to be turned
off in the first place but for some reason it does. once you get it
displaying the programs it shouldn't give you any more trouble.

Here's what's wrong or to be added: first, i want to get rid of having to
turn the calc off and back on. second, i want empty menus to be completely
empty - currently the first choice in an empty menu has a space char in it
which is sort of dumb. if anyone knows how to display an empty menu please
e-mail me. third, i want to fix the EDIT menu also so that it only displays
editable programs. fourth, right now i think editable ASM programs may show
up under BASIC and non-editable BASIC programs may show up under ASM. And
finally "Asm(" is put in for you even if you select a blank option in the
ASM menu.

I'll be fixing these problems and if any of you have suggestions then,
well... it'll go faster.

    Later,

P.S. Here are some addressed i found while writing this program: calling
$5420 with a character in A will write that character to the homescreen,
which is useful in (sqrt)KEY programs. Also, if you have a pointer to the
beginning of a string or a program in AHL, calling $521D gets the size of it
into DE and increments AHL by 2.
