hmm wow wonder where u got that one from :) you can use a routine that
is easier to follow and is a little smaller (no need for another jump)

jp nz,wherever ;jump wherever if the condition is false
ld a,1
now add a jump to a diff label or something else here

(you dont need the z on ret z)

yeah if you make a table, that confuses me more than doing single keys
tho and still would end up about the same size so you probably should
just keep the routine you have now

you have to use the OPs to load a variable and then use another call to
display it. look in the inc file for loading them and check out zreduce
for displaying
