No,nononononon :)...I said that was an idea, I never actually tested
it...but it should work, it should look something like this:

.equ keypad 0ffh
.equ Group1 0dfh

.org 9237h
  ld a,keypad 			;resets the keypad.
  out (1),a			;'Required syntax' :)
  ld a,group1 			;Enable group 1.
  out (1),a 			
  in a,(1) 			;'Required Syntax'
  cp whatever...

That's what you're doing yeah?...that should work.  If not...looks like I'm
wrong then :)

If you still have troubles, ask me...

Later,

James.
