ld hl,stuff ;Load the memory adress of first byte into hl
ld c,4 ;Load c with the value you want to break the loop
Loop: ;Place to come back to if not the right value (Label)
ld a,(hl) ;Load a with the byte stored at the adress hl
inc hl ;increment the aderss to the next byte
cp c ;compare the value in c with a, if the same set zero flag
jr nz,Loop ;Go to the label Loop if the zero flag is not set
Hope this helps.
