And another question: I get an error "! Illegal unit of measure (pt
inserted)." Is it really possible to divide a dimension by another
dimension? Not according to what I read here: http://www.tug.org/utilities/plain/cseq.html#divide-rp
"must be a nonzero integer." See, I'm far from being a native
speaker of TeX...
