12. DEBUG:


    This option allows you to view the X and Y data points in a
tabular format.  You may specify which curve to view if more
than one curve has been defined.  Termination of this option is
possible without viewing all data points.  For example, if an
error is detected in the third data set, you may stop the 'dump'
without viewing all 1000 pairs.  No editing of the data is
possible from within this option.
