Abstract

For a context-free grammar G , a construction is given to produce an LR parser that recognizes any substring of the language generated by G . The construction yields a conflict-free (deterministic) parser for the bounded context class of grammars (Floyd, 1964). The same construction yields either a left-to-right or right-to-left substring parser, as required to implement Non-correcting Syntax Error Recovery as proposed by Richter (1985). Experience in constructing a substring parser for Pascal is described.
