Yes, I think I can see how to do it. I can't see how to
do it in a couple of lines of code. And I can't see how
to do it without either using EXECUTE or FOR loops. But
I think it can be done.

Is this worth something to you? :-)

This would be a couple of hours worth of effort to
write a completely general program. For example,
you will probably have to write some kind of
recursive function to copy tag values that are
pointers and/or structures, etc. Just that alone
will take a couple hours, probably, although I
used to have something like that laying around
here.

Cheers,

David
