Hi Victor, thanks for your message. I agree that it would be good to
extend the functionality of the Runge-Kutta program, but instead of
writing a new program, I would like to ask you to modify the existing
program to implement the new feature. That way any improvements
that have been made already to the existing program are not lost.
You can post a patch (i.e., file difference as shown by diff or fc) or,
if that doesn't work, then just post the whole new file.

best,

Robert Dodier
