Another method for drawing characters to the screen (and quite legal) is to predraw the the characterset into an offscreen buffer and use copybits to blast their images to screen. This is what Red Ryder does. It is very fast because in the long run DrawString and DrawChar both call copybits eventually. If your character set is a mono-spaced font you can use the byte itself as an index into the offscreen bitmap. keith My hardware on Apple hardware, software flowing. A9F4
