OVERPLOT/IDENTIFICATION [table] [xpos] [ident] [ypos]
	overplot line identifications
\us\pu
Purpose:    Overplot line identifications on the already displayed spectrum.
            The position on the x-axis and the corresponding identified lines
            are defined in two columns of the table.

Syntax:     OVERPLOT/IDENTIFICATION [table] [xpos] [ident] [ypos]
\ys\pa
            table     = name of the table with the line identifications;
                        default: LINE
\ap\pa
            xpos      = reference to column with positions. The column must
                        be of REAL*4 type; default :X
\ap\pa
            ident     = reference to column with identifications.
                        The column can be of any type. The display
                        format of the column is used in the plotting;
                        default :IDENT
\ap\pa
            ypos      = code to define the vertical positions of labels
                        as TOP (default) or BOTTOM
