* All lines beginning with an asterisk followed by at least ONE
* blank is a comment and is ignored.

* The "auto" option now implies that BOTH the X and Y axes are to 
* autoscaled.  The average value of the variable "run" is now to be
* extracted from the file "r10" and included in the text string in
* an I4 format.  The curve wll now be drawn with a dashed (line type 2)
* style line connecting the data points, in the order they occur in
* the file.  X- and Y-axis labels have been added.
