You will definately need one of the replacements. (2) Lines/screen is located in 40h:84h. If you change that to 21, a modified ANSI.SYS might scroll properly. Programs that write directly to the screen or use BIOS to position the cursor will probably not be affected. Clear Screen (CLS / Esc [ 2 J) will probably clear the entire screen. Of course, your program to update the status bar may break. (Why do you need THREE status lines?) (3) I am curious if this will work. >Computin' in Texas, Larry Liska -- a_rubin@dsg4.dse.beckman.com My opinions are my own, and do not represent those of my employer.
