i got an e-mail from someone telling me how to display registers.
first you load the value into hl
call _disphl
but first you have to load the currow and curcol values
ie: ld hl,0303h ;coordinates for the homescreen
ld (currow),hl ;ld hl into currow
ld hl,05h ;whatever the number is that you want to disp
call _disphl ;display it
