Many thanks to all of you.
All the answers provided useful ideas and interesting points for further reading.
As always (... unfortunately ...), the most direct way to a solution of my problem was a kind "RTFM"
(Thank you, J=F6rg ;-) ).
So this thread can be considered as "solved".
Kind regards
Timm
