When set to "1" (on, true, yes), this variable disables color output for
MS-DOS machines with graphics video cards. The default value is "0" (off, false,
no).
ACUCOBOL-GT assumes that all MS-DOS machines with graphics video cards are
color machines (because the card has color capabilities). If you have a
monochrome monitor attached to such a machine, the results can be difficult to see. You
tell ACUCOBOL-GT to disable color output for these machines through the
MONOCHROME variable. When this variable is set to "1", ACUCOBOL-GT uses only black
and white.
