[From Rick Marken (970105.1950)]
I guess my ISP saw my post and fixed things up.
I put the Java source programs (called "classes", I guess) on
the net at my site. You can get to them from:
http://www.leonardo.net/Marken/demos.html
I hope they are comprehensible. If not, get some help from someone
who understands Java -- not me;-))
Best
Rick
