If I remember correctly, you can't do this. You either use "movel.l #0,a1" (which takes 6 bytes) or better (only 2 bytes) "sub.l a1,a1". > moveq.l #4,d2 > lea harpo(a1),a1 > myloop: > ... ; use a1 but keep it > adda.w elem_size,a1 > ... ; use a1 but keep it > dbra d2,myloop > lea chico-4*elem_size(a1),a1 > > Question: what is the value of a1 at the end ? I think harpo+chico+elem_size, though I am not sure whether the loop is executed 4 or five times... Joachim
