You're going to have to do a little bit more than poking. The way those machine language programs accomplish that is that they change the color of the text/background/border BEFORE the electron beem has time to scan down the entire screen. They change the colors so fast, that it appears that there is different colored text on the screen at the same time. The ONLY way this is possible is using critically timed machine language subroutines. >TSEMM@Alaska.Bitnet >TSEMM@Acad1.jnu.alaska.edu >TSEMM@acad1.alaska.edu ---------------------------------------- Michael J.
