Re: A82: get key




let's see.. this is off-hand, so don't complain

GK_loop:
	;	push hl	;the docs say that hl is altered, so if you want
			;to keep it, add this command
	call GET_KEY
	;	pop hl	;add if you add the push
	or	a	; any key pressed?
	jr z, GK_loop	; zf=no key
	cp	G_2nd	; was it the 2nd key?
	jr z, GK_loop	; if it was, continue looping.
	;etc....

that was with "GETKEY"... as for port reading, i'm a little shabby on
that, so i can't answer that one.
