I'm doing some graphics-intensive stuff on my ST, using Megamax C. Some of it involves animation, and it really looks bad to draw elements of the output piece by piece. The time taken is significant, and it would be a great improvement to draw the whole thing off-screen, in some phantom area, and then reset the screen position. Then the new drawing would just "blink" into place. But as far as I understand it, the drawing routines (v_pline, v_fillarea, etc) work only on the current screen. If anyone knows a way around this problem I'd appreciate hearing it. -jp
