An observation on suffix redundancy in LL(1) error repair

  • Eberhard Bertsch


We give a simple grammatical characterization of the notion of suffix redundancy presented procedurally in a recent article by Fischer and Mauney. It is shown that certain properties of grammars related to suffix redundancy can be decided at parser generation time. Some suggestions concerning efficiency of repair attempts conclude the article.
