Hi-

How can you display the key code of a keypress gotten from B_CALL _getKey on the screen?

thanks in advance!

I would store it to HL and use _DispHL:

Code: [Select]

ld hl,0
 ld (CurRow),hl
 bcall(_getKey)
 ld l,a
 ld h,0
 bcall(_DispHL)
 ret

You can!
You should use Hot_Dogs asm tutorials then z80 in 28 days. (I finished that in like 5 days, gonna reread it a few times)

That is probably the best method (reading it a few times). You won't absorb everything at first, but as you get practice and you learn something new, it will eventually all get absorbed :D

You should. There were always things I missed each time I read it. It's actually interesting to read, too :D
