        LAS\BOX [Arg1] [Arg2] [Arg3] [Arg4] [/UNIT Type [LOWER|UPPER]] [/IN-
    DEX] [/OBS]

    BOX draws a frame suited for the current R spectrum or index in  memory.
    The  units and limits are determined according to the options of the SET
    command (SET MODE ; SET UNIT), and the box size governed by SET BOX.

    Arg1/Arg2 modify the labelling of the lower (left) axis
              = P for parallel   labels (default for X axis)
              = O for orthogonal labels (default for Y axis)
              = N for no labels
    Arg3      indicates that the ticks are In or Out ofthe box
    Arg4      controls the labelling of the upper X axis and
              may have the same values as Arg1 or 2 (P, O, N).

    The default is BOX P O I.

        If present, it modifies (with no permanent action) the unit of the X
        axis  (lower  or upper according to the subsequent argument, default
        is LOWER). Type may be any of the usual SET UNIT arguments. For Con-
        tinuum  data,  the /UNIT command has no effect, but the unit is con-
        trolled by the SET ANGLE command. /INDEX produces a box  suited  for
        2D  color  plot  with  a  wedge (the Y-left axis gives the number of

        Plot a box for a single spectrum.

        Plot a box suited for 2D display: Y axis is the  temperature  scale,
        and  Z  axis  is the observation number. All three axis (X, Y and Z)
        may be defined by using the SET MODE command.
