An Error-Tolerant Top Down Parser.
ROYAL RADAR ESTABLISHMENT MALVERN (ENGLAND)
Pagination or Media Count:
This note describes a method of improving the performance of the top down parsers generated by SID or SAG, by incorporating automatic error recovery. The changes to the conventional parser are minor, and do not affect its performance significantly. Some preliminary results are given, showing the performance of the modified parser when applied to CORAL 66 and an assembly language.
