Problem:

I am using CodeView to debug my Presentation Manager (PM) program and
I am using the /2 switch to redirect the CodeView screen to a
monochrome monitor. When I press F5 to start my program, a protection
violation occurs, but it works correctly when I run it from the OS/2
command line.

Response:

The /2 switch for CodeView is not supported for Presentation Manager
application debugging. However, you may redirect the CodeView screen to
a monochrome monitor if you do the following:

1. Start a full-screen command prompt.

2. At the prompt, type the following command (this puts the prompt on
   the monochrome monitor):

      mode mono

   Note: You must be in a 25-line screen mode before you attempt the
   mode mono. If you are in a 43- or 50-line mode, the display is
   corrupted.

3. At the prompt, type the following command, where "appname" is your
   application's name:

      cvp appname

4. After you are finished debugging, you can return the prompt to your
   primary display by typing the following command:

      mode co80
