Similarly "shell display 132 >off", would switch the hardware back to 80 column mode. didn't want to make this into a huge thing, but let me explain this one bit further now. I can switch to maximum 132 by 60 mode at dos no problem. I can even switch the mode's in qbasic 4.5 by using a int call to the bios through a library I have, but to actually write in these modes and have the bios recognize it (i.e. do full scroll for 132 columns when it gets to the end of screen, etc..) and to also use locate statements and have them read in correctly is where I'm having my problem. The text either wraps around at the 80th column instead of #132 and if you do a locate 5,1 it will be skewed and the actual location would be ~ 7,40 or something.... it's all because qb 4.5 has that limitation on the width command. if it didn't have that limitation, then there wouldn't probably be a problem. Wonder if it's hackable :) Thanx for all the help anyways... but like I left the msg before this one, I went ahead and re-edited my programs to scroll within a section of space similar to the way you do it in windows. it's not as nice, but it'll do for the interim.
