RANDOM_MAP /SKIP

        [GREG2\]RANDOM_MAP /SKIP [TRIANGULATION] [INTERPOLATION]

    The option /SKIP will avoid recomputing the triangulation and/or  inter-
    polation,  in order to save time e.g. on large maps. Those optimizations
    are under the responsibility of the user, who should know if the context
    (e.g. variables) has changed or not. The command can not guess it by it-
    self.

      - /SKIP TRIANGULATION can be used if  the  triangulation  has  already
        been  done.  The  triangulation depends on the x and y values, which
        can come from the X and Y buffers or /VARIABLES Vx Vy, but  also  on
        the current plot limits.
      - /SKIP  INTERPOLATION can be used if gridding (interpolating) has al-
        ready been done. It depends on the z values, which can come from the
        Z buffer or /VARIABLES Vz. It also depends on the triangulation.

    Note  that the command may not honor the skip request if it detects that
    the context has changed. This is true e.g. at first call of the command.
