        Draws (or fills) isocontours of the Regular Grid array. The RG is an in-
        ternal 2D "map" created/loaded by various commands (RGDATA,  RANDOM_MAP,
        RESAMPLE,  IMAGE),  or loaded by a calling program. The levels are those
        specified by command LEVELS, but may be affected by a scaling factor  by
        option /PERCENT or /ABSOLUTE.

        This command is normally used in the following sequence:
        Greg> SET BOX LOCATION Gx1 Gx2 Gy1 Gy2  ! Define box position
        Greg> RGDATA (options...)               ! Put image in the RG variable,
                                                ! read associated header variables
        Greg> LIMITS /RGDATA                    ! Computes associated limits
        Greg> PLOT                              ! Plot the array in the box
        Greg> BOX                               ! Draws the box
        Greg> LEVELS 0.1 to 0.9 by 0.1          ! define contour levels
        Greg> RGMAP /PERCENT 1                  ! Draw contour levels  (in this
                                                ! case, as percentage of peak)

        The  "Quiet"  mode  does contouring silently. For "Fast" and "chunksize"
        modifiers, see subtopic MEMORY_OPTIONS.
