Assuming that you don't have any pointers hanging around. Which you can do ... make all pointers 16 bit integers and then whenever you make a pointer reference offset it by A4 (or whatever). But frankly, this would cause more harm than good and be awefully slow! More harm than good, because all those standard Amiga structures use normal 32 bit pointers, and one is bound to have a couple of them lying around! -Matt
