YACC(Yet another compiler -compiler),developed by Bell Lab,is a important software with UNIX,and can run on some other OS.It can generate the grammar analysis programs for most of context-free grammars.It is difficult to give the no conflicts syntax rules for complex grammar in YACC.In this paper,we describe the effective method of deleting conflicts for YACC.
