Thanks a lot. A lot of new stuff (for me) in your example.

I appreciate your advice. I have the impression one finds out about the
limitations only by diving into data structures a bit more deeply.
Although I haven't a clear picture yet what is possible and what is not,
I find some of the examples in Millers documentation quite intriguing.
