Are you, by any chance, running this on a Ti-84+ with OS 2.53? Make sure it's on classic mode if so

As much as I'd like to blame OS v 2.53 for this, switching the mode doesn't do anything.

Are you sure you're including ti83plus.inc? SPASM likes to pretend that it's correctly assembled a program, when in fact, it has actually replaced any bad opcodes or labels with 0. This is bad if you have jp badLabel.

You can check the source from the previous page. I included the file and I'm pretty sure I have the correct file, seeing as how I'm using the official ti83plus.inc. Using the one provided by TI doesn't change anything either. Also, the include instruction is from Buckydude himself. That makes me fairly certain of its validity.

That's not very good. I didn't know SPASM did that :(

Also, does the ti83plus.inc file define it b_call or bcall? That could make a difference, since it would then not include the bcall at all.
And you are using the ti83plus.inc for SPASM, correct? Other versions might not work.

If you're using the official ti83plus.inc from TI, that file uses ZMASM syntax for macros and equates.  I don't think spasm supports that syntax, or at least, it didn't the last time I checked.

Also, the official syntax defined by TI is "B_CALL PutS", not "bcall(_PutS)", so if you're using the official ti83plus.inc, it doesn't surprise me that the latter doesn't work.

It might help if you could post a listing file.

There are many different versions of ti83plus.inc floating around out there.  Which two, specifically, did you try?

For TASM - and I assume this would also work for SPASM - you'd want to include something along these lines, at the top of the file:
Code: [Select]
#define bcall(x) rst 28h \ .dw x
#define bjump(x) call BRT_JUMP0 \ .dw x
#define equ .equ
#define EQU .equ

Back in the day, when I used TASM, I liked to add:
Code: [Select]
.addinstr B_CALL * EF 3 NOP 1
.addinstr B_JUMP * 0050CD 5 NOP 1
which lets you write "B_CALL _PutS", a little bit closer to TI's official syntax.  I don't remember if SPASM supports addinstr.

In addition, you probably need to comment out the macro definitions later in the file.
