        [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.
