This is a follow up on the thread on parsing that took place
some time ago. I just completed a very initial stage version
of a yacc/lex skeleton parser. It does only orcs for now
and does not do semantic checking. You can find it in the
AIMI csound site:

ftp://musart.dist.unige.it/pub/CSOUND/csound-parser-v0.0.tar.gz

(there's also a zip version for tarless systems).

Enjoy,

nicb

Re graphics: A picture is worth 10K words -- but only those to describe
the picture.  Hardly any sets of 10K words can be adequately described
with pictures.
