Hello Jim,

Please see the FAQ:

I didn't find an answer there,

Or there.

This may be more like it:


but that just turns off recovery, it doesn't provide a "cut" as in Prolog
and other grammars.

It's not just a matter of reporting errors as close as possible to the
offending phrase. The parser can be much more efficient if it knows it's
committed to a given rule once a certain phrase is seen.
