Pointers to information regarding existing syntax-directed editors
for C would be appreciated.  If interest warrants it I will post
any results that I get.  Thanks!

Mark Horton wrote a monster sized (he says it needs ~2Mbytes of core)
sde for C at Berkeley.  I've been asking for a copy for ~2 years
now, and he's very reluctant to part with it, but you might try
him.

At the Spring '84 EUUG conference in Nijmegen, The Netherlands,
Theo de Ridder from IHBO "de Maere" in Enschede (...mcvax!im60!ridder)
presented a paper

	"Automatic Generation of Syntax Directed Screen Editors"

	Abstract:
	From a new effective and automatic error-recovery
	scheme for LALR(1)-parsers a program generator is
	developed that produces a syntax directed screen editor
	for any language specification written in LEX and YAAC.

The paper says they were working on a specification for C. It also
says the size of 85% of the compiled editor code is ~55K bytes, a
long way from 2M bytes.

As an aside, when trying to write a specification for the Bourne Shell,
Theo discovered all those wonderful loopholes like
	<<`echo "Goodbye World"`
which cause hours of endless amusement at conference exhibitions.
(One machine we tried it on had to be restored from floppies).
