Well, someone else can fill in the specifics since I don't remember the BIOS call functions off hand but if you're using an EGA,VGA video card you can call the INT ??h (10h?) that normally initializes the screen mode with a value that tells it not to clear the screen. Pick up any Assembly guide for the BIOS calls and look it up. Unfortunately, CGA and I believe MCGA modes always clear the screen and cannot be avoided. In these cases you have to either already be in graphics mode, or reprint the text. Hope I was of some help, you can mail me for more info and I'll take the time to look up the actual values. Although someone will probably post them Jeff Bakke NU113738 at NDSUVM1.BITNET
