Basic is easy...
Do this:
Create a programm called OFF (or summit like that) and do the following:
2nd, 0 (catalog), down 8 times (AsmPrgm), press Enter.
Now your program is:
PROGRAM:OFF
:AsmPrgm
:
now make so its:
PROGRAM:OFF
:AsmPrgm
:F33E01D303FB
:C9
That may be confusing, but just do as I say

Now once you have it as
PROGRAM:OFF
:AsmPrgm
:F33E01D303FB
:C9
go to the home screen and press 2nd, 0 (catalog), down 6 times (Asm()
then go to the program list and find OFF (or whatever you made as)
Now your homescreen is:
asm(prgmOFF
press enter. boom, there goes your screen.

press on now, it will be right as it was left... only with the "Done" from creating a program.
If that does something to your calc, not my problem. never did anything to mine. (ASM has a tendancy to clear your RAM if misused...) But this is cool anyways. If you put that in the middle of a program, it just freezes untill you press something like 2nd Off On On or something like that...
This is that wierd
[codebox]#define B_CALL(xxxx)
#define B_JUMP(xxxx)
aaaaaa.org 9D95h
aaaaaaDI
aaaaaaLD A,001H
aaaaaaOUT (003H),A
aaaaaaEI
aaaaaaRET
.end
END[/codebox]
was.
Another cool thing about ASM is on my calculator if I press Alpha (or Alpha Lock) it will do the normal capital letters; but if I then press Alpha again, instead of going back to the normal (numbers), it does lowercase letters! then if you hit again goes to normal (cycles through ALPHA alpha number)

Its an ASM program that adds something to your calculator and makes it cool.
Wow maybe that thing is why my ARC memory is 2541K (litterally has the K)
