Re: A83: label from input
dont bother using jp (hl) in this simple of a routine
the only time jp (hl) can be useful is in a situation where you would need
to execute multiple RETs to escape from a subroutine.
besides even if you used jp (hl) you would have to do a "cp" to set hl in
the first place
so just use cp xx , jr z,xxxx
