BOX

        LAS\BOX  [Arg1]  [Arg2]  [Arg3] [Arg4] [/UNIT Type [UPPER]] [/INDEX]
    [/OBS]

    BOX draws a frame for the spectra. 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(2)  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

    /UNIT
        If present, it modifies (with no permanent action) the units of  the
        X  axis, or only of the upper X axis if UPPER is specified. Type may
        be also IMAGE to get image-side-band frequency units. For  Continuum
        data, the /UNIT command has no effect, but the unit is controlled 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 spectra).

    /OBS
        Plot a box for a single spectrum.

    /INDEX
        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.
