        [DISPLAY\]SHOW Argument [Arg1 [Arg2]] [/DIRECTORY NameTree]
      [/OVERLAY [Variable [Channel]] [/SIDE]

    where
    Argument
        is  a  Keyword (e.g. COVERAGE, NOISE, UV_FIT or MOMENTS), the name of an
    internal buffer to be plotted (BEAM, CCT, CLEAN, DIRTY, etc.. ),  a  2-D  or
    3-D  SIC image variable or datacube filename (in Gildas or simple FITS image
    format).

        [DISPLAY\]SHOW ?
    will list the names of recognized keywords and buffers.

        Except for UV data where they have a different meaning,
    Arg1 and Arg2
        are optional arguments to restrict the range of channels to be  plotted.
    They  default  to  FIRST and LAST variable values respectively, and Arg2 de-
    faults to Arg1 if only Arg1 is specified.

    The UV data in the internal buffer is the one loaded by command READ UV File
    and optionally resampled by UV_RESAMPLE, UV_COMPRESS, etc..., or transformed
    by UV_CONTINUUM. Flagged UV data  will appear in a different color.

    Command VIEW offers a different style of display for cubes, NOISE  and  CCT.
    Command INSPECT_3D offers another style for cubes.

      The  /DIRECTORY  option allows to the user to simultaneously display (same
    or different) data in different ways, as each display is then affected to  a
    different "graphic tree" that inherits a specific window.
