Thanks a lot for this very valuable hint. However, I'm having problems
with fps-1.0 in combination with scsh-0.5.2 when I try to use
fonts. Immediately after starting scsh and loading the fps package I do:
> (font "Helvetica" 12)
Error: exception
(cdr '())
Hmm? Have you also encountered this problem during your 'porting' and can
you give me a hint how to solve it? (I also have contacted Olin Shivers
about it.)
Many thanks again: This is exactly what I was looking for (if I get the
font thingy to work :-)
