Thanks Brian,

I downloaded your file and it ran fine. I studied it and modified it
to learn how to use it and I think I am catching on a little. At any
rate I can import sections of it into my own programs and get good
results.

The thing that puzzles me most is that apparently the limit to radio
buttons in one window is tree and push buttons are limited to two. It
seems to me that those are rather low numbers. Why not allow as many
buttons as one can fit in a window? Ok I am not a programmer anymore
(I used to be decades ago) but it seems that would not have been much
trouble to the clever programmers that write this stuff.
