Babaoriley: Rainer, for a guy for whom English is not a first langauge, you certainly have a way with the language!  Love the above, I can see the dam bursting!

Thank you, Babaoriley, you are welcome! Yes, I love text and language and love to discover more subtleties of the English and German languages, and learn to use them actively. In fact, although I am a computer scientist, documentation is an important part of what I am (still) doing for a living, like this.
