Oh, dear!
What I first thought was "impossible" now appears
to be do-able, but probably not as implemented
in this version of the program. The problem now
is that this works great for a single command in
a resizeable window, but it doesn't work properly
for multiple commands in the window. Plus, I need
the ability to evaluate parameters as well as keywords.
Oh, well. No one said life was easy. :-)
Back to the drawing board. (But, with more
optimism than I had when I started this project!)
Cheers,
David
