Thanks for the rapid replies (again),

Certainly I will not write my own macros for that, I know you can't win
compared to the build in code using an interpreter like VBA.
It is a pitty Array.Sort has not been implemented , would help a LOT of
people I think.
For identifying if a set is unique while filling the sets I already
created a key consisting of a "concatanated" string (actually summing
the values of the columns each multiplicated by a constant specific for
that column) and considered sorting on them. I guess I will need to do
that as I found nothing else.

Thanks for the help
