            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.
