Hello Michael,

that helped me a lot, was exactly what I wanted to do at least as
startpoint. :)

I think it didnt just did silently nothing, but could be wrong :).

Hmm yes I am a lisp beginner I still strugle with the different lists
and even somethimes have problems to understand the concepts behind it,
and what is a good/efficiant/clean way to code. :)

Well I guess I misread the description. Each has the form, so the
additional parenthesis makes sense, but why is a ' needed for entries
but not for format?

Because its "either a function or a list, and
therefor it tries to execute the function of nil". So whenever I read
such sentence I have to quote? Or do vectors get quoted / not evaluated
in general?

Yes it works and making "something happen" was exactly my goal :)
