Summary: 
This paper describes an error-correcting parser for a context-free language based on the Graham-Harrison-Ruzzo's context-free recognizer (GHR). The parser has similar characteristics as GHR:
(1) The parser unifies both the top-down error-correcting parser by Lyon and the bottom-up error-correcting parsers by Tanaka-Fu and Yamasaki-Tonomura.
(2) The parser is conceptually simpler than the Lyon's parser, and may be much faster than the bottom-up error-correcting parsers.
