Thank you very much, that works indeed.

But here \dimexpr is nonsense (should have seen that before).
But "scale=1000\LPscale" just concatenates the two "strings", and TeX
doesn't seem to reckognize a *
How can I multiply two values? Di I need some expansion magick or
just something like "eval()"?
