  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.
