I most humbly agree. 

Some suggestion to the original poster as to recursive-descent error recovery:

Al Hartmann: An implementation of Concurrent Pascal
Springer Verlag

	Contains a description of a way to produce RD parsers with error
	recovery, based on the methods used in the Zurich P4 Pascal.

Steven Pemberton: Comments on an error-recovery scheme by Hartmann
Software - Practice & Experience, 

	Corrects an error in Hartmann's description. This is probably
	the best place to start.

(I'm typing these references from memory. Titles are probably off by one,
authors and publishers are not. Hope it is of some help.)
