you are telling the program to stop if there is no key pressed (ret z) also take out ld (hl),a and replace it with: ld l,a

ld h,0

ld a,0

call $4a33

This simple bit of code is designed to display the contents of "a" (received from the GET_KEY call) at the top of the screen. Since it's going so fast, you should only see a byte when you're holding down a key. I'm not getting anything. Can someone see the problem?

-------------------------------------------

#include "ti86asm.inc"
#include "asm86.h"

.org _asm_exec_ram

ld hl,$FC00
call _clrLCD
loop:
call _clrLCD
call GET_KEY
cp $37
ret z
ld (hl),a
jp loop

.end
----------------------------------------

Thanks
