I used to be a C64 hack a few years back and remember that when I wanted to do animation (fullscreen bitmap) all I had to do was allocate 2 separate buffers in RAM and while one was being displayed, draw the next frame in the other buffer. Then to display the other buffer, all I would have to do is change the pointers to the bitmap area. Real simple. Well, according to my TC 2.0 and TP 5.5 books, I cannot do this in CGA!!! They say that there is only ONE graphics page available in CGA, but other graphics modes seem to have at least TWO. But I find hires 3D animation demos and programs (like Stellar-7 and numerous commercial flight simulators) that animating rather quickly. So, is there a simple pointer I can adjust so I can flip between buffers? Or will I have to do bitmap copies? Or is there another option? Thanks in advance! - -- David
