[A83] Re: Displaying Characters




I am trying to display numbers on the graph screen that are stored in in a
string 'A' and then decrement them. SOCCERK121 helped me with displaying
them on the graph screen by:

ld a,(a)
ld h,0
ld l,a
bcall(_Setxxxxop2)
bcall(_op2toop1)
ld a,5 ;<--- number of digits, 5 is a safe number
bcall(_dispop1a)

 
But whenever I dec the A like this:

 ld hl,A
 dec (hl)

A: .db 0h

It messes up and from then on displays the number 255 whenever i reuse
SOCCERK121's routine.
I don't know wether its because A is a hex number or if I am doing something wrong.
