Heres the code(LateNite,Brass):

I can't think of anything other than incorrect syntax for your particular IDE.

What's your setup?

The only thing that I can readily see is that there's no header.

Apart from that, I can't see what's wrong with the code. If whatever assembler you're using is producing errors or warnings, it would be much appreciated (and helpful) to post those too.

Try running your program through a shell like MirageOS or CrunchyOS.

maybe you should try looping until a specific key (other than typical selection keys to run the program) is pressed. if that still doesn't work, then it could be an assembler issue.

Try replacing b_call() with bcall().

Also, instead of b_call(_GetKey), try something like this:


Code:
-  bcall(_getCSC)
    cp skClear
    jr nz,{-}
    ret

I don't think that is the issue, as _getkey is pretty slow to recognize a key press. Are PLOTSSCREEN and the bcalls defined?

A typical header for the 83+ might look like this:

Code:
#include "ti83plus.inc"
     .org progstart - 2
     .db  $BB,$6D


I don't know how Latenite/Brass function, but if it spits out a .lst file if you could paste that here that might clear some things up.

EDIT: And if it isn't recognizing b_call(), you can do what benryves said or add this line:

Code:
#define b_call(xxxx) rst 28h \ .dw xxxx
Though i don't know that that is the problem if you are getting an .8xp file.

If using the templates bundled with Latenite, do not add a header, as they are defined with the template (externally to the main program source code file). Improving the signal to noise ratio and all that jazz.

If he made the program for a shell it would quit immediately, because the shell header starts with $C9 (ret). I don't know what the latenite things do though.

Thanks all that posted and Benryves.

I replaced B_call with bcall and it fixed it.

Why is this though? Does latenite use bcall instead of B_Call?

It works.

Also you don't need headers in Latenite.

Yes. If you'd like to use b_call you can open the file "TIOS Calls.asm" and replace the declaration in there.

Code:
.define bcall   rst rBR_CALL \ .dw _

This is also defined, so bcall GrfBufCpy will also work (note lack of _).
