I was interested in any published research material dealing with syntax
error detection and recovery for LL(k) or LR(k) parsers. I am really
interested in the "recovery" methodologies employed by parser generators.

Also, in regards to the very popular YACC parser generator, I was
interested in any research done in the area of maximizing the error
detection and recovery capabilities of a YACC generated parser by managing
the "proper" placement of error productions in a grammar.

Please direct any information and/or comments to:

Thanks in advance.   Vince George.

[There has been considerable discussion of this in the past.  Yacc's
default reductions make error recovery hard, since by the time it realizes
there's an error it may have lost much of the context that one would want
to use to recover from the error. -John]
