\us\pu
Purpose:    
            Overplot the contents of a keyword
\up\sub

\bus\sy
Syntax:     
            OVERPLOT/KEYWORD [key_name] [start,end] [offset]
\ys\pa
            key_name  = name of the keyword; default is OUTPUTR
\ap\pa
            start,end = first and last data point to be overplotted; end
                        can be smaller than start; defaults are the first
                        and the last valid data points in the keyword
\ap\pa
            offset    = offset value in the y direction (world coordinate 
                        units); default 0.0
\ap\no
Note:       
            After the overplot the last (over)plotted data set is the active
            one and subsequent commands will work on these data.
