Following Uwe's suggestion, I arrived at
@Circle margin {0.2f} @Circle margin {0.4f}
which looks much better. I'm sorry, but I can't find the information you're
referring too (I'm probably too tired or too stupid, or both).

Sounds good, too. I'll try this and compare it with Uwe's approach.

Yup, I've read this, and I had already planned to use @Tab for more serious
stuff (see, I do read the manual :-)
Thank you very much for your time and support. I hope I'm not bothering you
too much and that I'll eventually learn the ropes of Lout (heck, I just had to
learn a very ideosyncratic language for writing Left-Associative Grammars on
which I'll be examined on Monday--I should be able to learn Lout, too :-).
It's definitly worthwhile, I think.
Thanks again
