When set to a non-zero value, this variable disables color output for Windows machines with graphics video cards.
ACUCOBOL-GT assumes that all Windows machines with graphics video cards have color monitors (because the card has color abilities). If you have a monochrome monitor attached to such a machine, the results can be difficult to see. You can tell ACUCOBOL-GT to disable color output for these monitors through the Monochrome option. When this is set to a non-zero value, ACUCOBOL-GT will use only black and white. The default value is zero. Note that you may change this in your program by using the SET ENVIRONMENT verb; ACUCOBOL-GT examines the MONOCHROME setting each time it does screen output.
