When debugging a graphics application, there are a number of Watcom Debugger
command line options that could be specified depending on your situation.

 1. If you only have one monitor attached to your system, use the "Swap"
    option.  The "Swap" option specifies that the application's screen
    memory and the debugger's screen memory are to be swapped back and forth
    using a single page.

 2. If you have two monitors attached to your system then the "Two" and
    "Monochrome" options should be used.  The "Two" option specifies that a
    second monitor is connected to the system.  Note that if the monitor
    type (Monochrome, Color, Colour, Ega43, Vga50) is not specified then the
    monitor that is not currently being used is selected for the debugger's
    screen.  If you specify "Monochrome" then the monochrome monitor will be
    used for the debugger's screen.

 3. If you are debugging the graphics application using a second personal
    computer and the remote debugging feature of the Watcom Debugger then
    the choice of display and operation mode for the Watcom Debugger is
    irrelevant.  If one system is equipped with a graphics display and the
    other with a monochrome display then you will undoubtedly use the system
    equipped with the monochrome display to run the Watcom Debugger.
