Re: A83: Re: Re: Problem with a program
Or you could do something like this:
ld b,0
ld c,b
Loop:
djnz Loop
dec c \ jr nz Loop
I think that's what James meant.

djnz only works with b. If you want to loop >256 times (if b=0 it will loop
256 times with djnz), then use bc like this:
ld bc,20000
loop:
push bc
;...code
pop bc
dec bc
ld a,b
or c
jr nz,loop
