            [GTVL\]LUT [Argum] [/PEN] [/REVERSE] [/BLANK Color]

        Modify  the bitmap or pen look up table. Option /PEN indicates to modify
        the value of the 16 user-controlled pen colors (colors 8 to  23)  rather
        than the bitmap look-up table.

        The default argument is LUT. Possibles arguments are:
        - ?
            Type  "LUT ?"  to display the list of available LUTs, or execute the
            demonstration procedure @ gag_demo:demo-luts.greg for  an  overview.
            One  can  use  alternatively  the  LUT editor (button "Edit Lut") to
            browse and edit the LUTs in an interactive widget.

        - LUT
            A  custom  color  model  can be defined in RGB or HSV arrays and ap-
            plied. See subtopic LUT for details.
        - Any other LUT Argum will read Red Green Blue values from the formatted
            file named "Argum". See subtopic FILE for details.

        The  LUT,  whereever  it comes from, can be reverted before use with the
        option /REVERSE.
