I'm not sure what would have saved bacon in the above case. I don't see how your example would work. I think it contained a typo. In what I think you were trying to demonstrate, I would just pass $x by reference (&$x) -- or -- return $x by value. I would not have used a global, In any event, I seldom use globals anyway. This was more an academic discussion. Cheers, tedd _____________________ tedd.sperling@gmail.com http://sperling.com
