thanks, that's the key!

this can be split - if the successpage is not set or the same as the
current page, it seems to be sufficient to write "$action='browse';"

This should do the job, thanks for the hint. I'm a bit conservative in
using functions I don't know, and I even had problems to understand
Redirect() completely. It took me a while to understand that
FmtPageName('$PageUrl',$pagename); does nothing else than converting
$pagename to the corresponding URL. Isn't that a rather expensive
operation for such a simple task? Not that it would matter, I'm just
curious.

No problem - this is a level where I can continue, thanks!

Good to know. PmForm is "lightweight" and basically does what I need.
Just the documentation contains a bunch of unanswered wuestions.
