Hi Thomas,
after looking a bit i found you are right. There may be some hacks to do
it without range types, but with range types it is straigt forward to
implement. I am not quite happy to upgrade to 9.2 because i just got
everything running fine on 9.1. But i think, i will do it this way.
Thank you for your help.
Wolfgang
