Error detection in LR parsing

Error detection in LR parsing. Errors are discovered when a slot in the action table is blank. Canonical LR(1) parsers detect and report the error as soon as it is encountered LALR(1) parsers may perform a few reductions after the error has been encountered, and then detect it.
