A 'forward move algorithm' and some of its formal properties are presented for use in a practical syntactic error recovery scheme for LR parsers. The algorithm finds a 'valid fragment' (comparable to a valid prefix) just to the right of a point of error detection. For expositional purposes the algorithm is presented as parsing arbitrarily far beyond the point of error detection in a 'parallel' mode, as long as all parses agree on the read or reduce action to be taken at each parse step. In practice the forward move is achieved serially by adding 'recovery states' to the LR machine. Based on the formal properties of the forward move we propose a practical error recovery algorithm that uses the 'right context' accumulated by the forward move. The performance of the recovery algorithm is illustrated in a specific case and discussed in general. (Author).

Abstract: "We present a method for recovering from syntax errors encountered during parsing. The method provides a form of minimum distance repair, has linear time complexity, and is completely automatic. It is incorporated into the LR parser-generator yacc in such a way that the compiler writer can generate a parser with recovery without providing any additional information to yacc [sic] Error messages phrased in terms of source input are generated automatically. We present a formal method for evaluating the performance of error recovery methods, based on global minimum-distance error correction, and show that the error recovery method presented achieves a theoretically best performance on 80% of Pascal programs in the Ripley-Druseikis collection."

The new error recovery techniques have been applied in an error checking program for Pascal. The recoveries produced by that program are shown to compare favorably with those produced by two well known error recovery systems. Finally, some drawbacks of the new techniques and some directions for future work are discussed.

This work is Volume II of a two-volume monograph on the theory of deterministic parsing of context-free grammars. Volume I, "Languages and Parsing" (Chapters 1 to 5), was an introduction to the basic concepts of formal language theory and context-free parsing. Volume II (Chapters 6 to 10) contains a thorough treat ment of the theory of the two most important deterministic parsing methods: LR(k) and LL(k) parsing. Volume II is a continuation of Volume I; together these two volumes form an integrated work, with chapters, theorems, lemmas, etc. numbered consecutively. Volume II begins with Chapter 6 in which the classical con structions pertaining to LR(k) parsing are presented. These include the canonical LR(k) parser, and its reduced variants such as the LALR(k) parser and the SLR(k) parser. The grammarclasses for which these parsers are deterministic are called LR(k) grammars, LALR(k) grammars and SLR(k) grammars; properties of these grammars are also investigated in Chapter 6. A great deal of attention is paid to the rigorous development of the theory: detailed mathematical proofs are provided for most of the results presented.
