Uuh interesting - thanks for the links!
I just wasn't sure about this, maybe mentioning it in the help chapter
for DIM would make it clear.
What I've done so far to overcome this: When I have string arrays, I put
in data with tabbed fields and unpack them line for line with Split.
It's a bit roundabout, but highly flexible and rather fast.
