Interesting that I just read a blurb in PC Computing (aug 1988) about ten minutes ago that mentioned this. It goes as follows: The 80286 is capable of multitasking when run in its protectd mode, which assures that one application won't corrupt the memory owned by another application. They also go on to say that this cannot be used int the DOS environment. That's all I know about it, if anyone can shed any further light, please do. ========================================================================= Greg Cook All good things come through chemistry! gcook@horus.cem.msu.edu cook@frith.egr.msu.edu
