Uwe,

thanks a lot!  Now I can go to bed :-)

The syntax is absolutly cryptic, but the result is magnificent!

I know that TeX (the language) and Lout (the languge) are based on completely 
different language/evaluation models, and I'm really fed up with TeX, I still 
think that creating personal extensions is easier in TeX and a somewhat weak 
point of Lout (even if Lout (the language) is, of course, much cleaner than 
TeX (the language)).

It certainly does--that's exactly what I wanted!  And I thought I'd tried all 
combinations of [hv]*margin...

It couldn't help more!  Thanks a lot!
