SLICE

            [DISPLAY\]SLICE VarName Start1 Start2 End1 End2 UNIT

          Cut a slice through the 3-D image variable VarName with the  specified
        edges  and  put it in the SLICED image variable. UNIT is a keyword indi-
        cating in which units the edges are specified. It can be PIXELS, DEGREE,
        MINUTE,  SECOND, RADIAN, of ABSOLUTE.  For ABSOLUTE, Start1 and End1 are
        assumed to be in hours and Start2 End2 in degrees, with sexagesimal  no-
        tation allowed.

            [DISPLAY\]SLICE VarName StartX StartY Unit ANGLE AngleValue

          This  alternate syntax allows to specify a point and an orientarion of
        the slice. The coordinates StartX StartY are in the angular unit  speci-
        fied by Unit (which can be ABSOLUTE) AngleValue is in Degree.  The Slice
        length will be automatically computed to intersect the whole cube.  This
        syntax  can  be more convenient to compare parallel slices, or slice in-
        tersecting at a common point that can be specified by StartX StartY.
