When I wrote my previous message, I was thinking along the
lines that if the answer is not in this thread, it will not be
anywhere else. I had looked at uni stat sites and not found
anything I was looking for.

However, I do use Google and decided to give it a try just
in case. Shock, Horror, I did get some hits. So now I have
to go away, read those hits and then come back and be
able to ask another clearer question about what exactly I
want to do.
