Whats the smallest Hello World program in Z80 ASM out there?
How is it optimized?

Do you have something against normal ASM source code? We don't generally deal with program already converted to hex, as the size of programs is immediately apparent from the human-readable source of normal ASM code.
I was wondering why an ASM program needs to have the compiled date. Could I put those hex numbers that have the date to 00?
The header isn't going to be stored on the calculator anywhere, so the size of the header is irrelevant when considering space taken on the calculator.
so how big is the Hello World program on the calc?
Program:
Code: .NOLIST
#define EQU .equ
#define equ .equ
#define END .end
#define end .end
#include "ti83plus.inc"
.LIST
.org 9D93h
ld a,0
ld (CURCOL),a
ld (CURROW),a
ld hl,text
B_CALL(_PutS)
ret
text:
.db "Hello, World",0
.end
end
I also went and researched the "ti83plus.inc" file and found that PutS is really address $450A and I could do address $4540 to clear the LCD.
That should be 38 bytes on-calc.
Edit: Also, those addresses are used by the assembler in the BCALL macro, so you don't need to use those addresses directly in your source code (in fact, you should not for readability). It's not going to affect the size of your program.
souvik1997:
what do you mean about taking out the BCALL's?
