        PLOT  will  put a pixel image (pixels contained in the variable Varname)
        inside the current BOX. Varname is a 2-D SIC variable name that defaults
        to  the  RG  variable if omitted. Subsets like A[4] where A is a 3-D sic
        variable are not yet allowed. How to create and handle  images  in  pro-
        grams  calling  the GREG2\ language (including GREG) is described in the
        subtopic IMAGE_HOWTO.

        This command is normally used in the following sequence:

        Greg> SET BOX LOCATION Gx1 Gx2 Gy1 Gy2  ! Define box position
        Greg> RGDATA Varname /VARIABLE          ! 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
