The reason for his is that 132 column mode is much hardware dependent.
Different Video Boards have different commands to change to this mode. Without
the right Video Hardware, you may not even be able to use 132 column mode.

As far as Qbasic is concerned, if your variable is 132 characters wide, you can
put 132 characters in it, regardless of the screen width, but to get the screen
width to 132 columns, you'll have to write something to tell the video board to
go into 132 column mode. In my system, I can use a dos command "display 132 on"
to change video modes. This calls "display.com" to change the setup.

From Qbasic, I would issue the command "shell display 132 on" from the program
to cause the video to switch to 132 column mode. Similarly "shell display 132
off", would switch the hardware back to 80 column mode.

The construction of the call to "shell" in Qbasic, would be dependent on your
particular hardware. It's usually a combination of both the Video Board and
the monitor in order for 132 columns to work. Some monitors don't support the
scan rate and fonts necessary to do 132, even tho the Video board may support
it.

Check the book on your video board to see if it supports 132. If so, it should
tell you how to do it from the command line. Try it. If it works, then you
should be able to use "shell ....." to do it from a Qbasic program.

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.
