SPECTRUM

        LAS\SPECTRUM [ArrayName] [Yoff] [/INDEX] [/OBS] [/PEN Ipen]

    /OBS
        Plot the spectrum in the R buffer in the units and scales defined by
        SET  UNIT  and  SET  MODE. No argument or argument "Y" will plot the
        spectrum Y intensities of the R buffer (RY), but an associated array
        can be plotted instead given its name.

        Yoff  (default 0) is a constant Y-offset added to the plotted values
        (useful to compare two spectra).

        The option /PEN allows to use a i-th pen instead of the current one,
        without modifying it in return.

    /INDEX
        Plots the 2D array from the last LOAD command.

    Without  option,  the behavior depends on SET ACTION (see PLOT). Default
    is OBS.
