            MASK

        This  task masks either the inside or the outside of  a  polygon  in all
        planes  of a data cube.  It is similar to  the  MASK  command  in  GreG,
        GRAPHIC or OVERLAY, but it does affect  the  output  image  and  not  an
        internal  copy  of  it.   The  polygon must have been created previously
        using the WRITE POLYGON command in GreG, for example.
