本程序不能编译除大小写字母之外的编码 本程序需事先建立字母权值文后件才可运行 本程序从文件中读入文字，编译后写入文件，所以屏幕上不会直接出现答案...

现将本人搜集常用的程序设计语言的词法和形式文法提供给大家。其中，词法是按LEX格式编辑，形式文法是按YACC格式书写，大家可直接用LEX和YACC工具编译生成各类程序设计语言的分析器。-commonly used programming language syntax and grammar forms to the public. Among them, morphology is based on LEX format editing, grammar form is written by YACC format, we can use the LEX and YACC tools various compiler generation programming language analyzer.
