            [GREG2\]RGMAP /GREY [start [step] [background]]

        On  graphic displays with area filling capabilities, fills contours with
        up to 16 different color pens (but the number of contours is not limited
        to  16).  These  pen colors may be changed in the same manner as for the
        pixels colors (see HELP LUT /PEN). "start" (default 0) and  "step"  (de-
        fault  1)  may  be used to change the exploration of the 16-pen palette.
        "background" is the number of a color used to fill the map  before  con-
        tour-filling,  thus providing a user-defined background for the contour-
        filled map.

        In case of Filling problems, see the  subtopic  MEMORY_OPTIONS  of  this
        HELP.
