Syntax
  SCREEN [mode][,[colorswitch]][,[apage]][,[vpage]]
 
  Argument      Description
  mode          An integer constant or expression indicating the
                screen mode. See Screen Mode Summary for a list of
                the valid mode numbers.
  colorswitch   Determines whether color is displayed on composite
                monitors. The colorswitch is a numeric expression in
                the range 0-255.
                  ■ When it is true (nonzero), color is disabled and only
                    black and white images are displayed.
                  ■ When colorswitch is false (zero), images are in color.
                  ■ The meaning of the colorswitch argument is inverted in
                    screen mode 0.
                In screen modes 2 and up, colorswitch is ignored.
  apage         A numeric expression that is the number of the screen
                page that text output or graphics commands write to.
                See Adapters and Displays for the number of pages
                available for each graphics adapter.
  vpage         A numeric expression that is the number of the screen
                page being displayed.
