Version 2 modifications to XYPLOTTER:

XYPLOTTER has several capabilities not available with 
the original XYPLOTTER graphics package, but continues 
to support all operations of the original XYPLOTTER.  
Some of the changes made include:

     1.  Title can now be 60 characters long, centering is optional.
     2.  The user now has the option to read in the data for up
         to three curves out of the same file.  (SEE HELP #3)
     3.  The user now has the option of having a grid drawn on the window,
         if this is desired over tic marks.  (SEE HELP #8)
     4.  Labels do not go to exponential form as early as they used to.
         Additionally, window edge labels may now be changed to
         words, expressions, etc.  (SEE HELP #9)  Minimum and maximum 
         labels are now located closer to actual window edges.
     5.  The user may now change curve labels under the plot.

     6.  User can keep from going to default window settings when entering
         new data.
     7.  The user now has the option of specifying different plot
         types on the same window.  For instance, one curve may be
         a continuous plot, while a second one is a set of points.
     8.  It is now possible to save plots under different filenames.
         XYPLOT will first try to save plots under "ln03.graph".
         If that file exists, it will ask if the user wants to
         write over the old one, or save it under a different name.
