你可以任意输入合法文法，给定任意的句子，将会分析出这个句子是不是文法的的句子-You can enter any legal grammar, given any sentence, it will analyze the sentence is not grammatical sentences! !

前些天写了个小语言的词法分析程序，因为前些天在VC知识库看到一个pascal词法分析的程序，觉得写得挺复杂的。其实词法分析程序的原理都是一样的，所以我想只要搞明白了简单的词法分析程序，再写复杂的就不难了，无非是多加几个关键字，多写几个条件判断语句而已。词法分析是编译程序的基础，也是最简单的。好，现在让我们看程序吧。 先让我们看看这个小语言的文法吧-few days ago wrote a small language lexical analysis procedures, because the other day in the knowledge base to see a VC pascal lexical analysis procedures, find that quite complex. In fact, lexical analysis procedure is the same principle, I think if you understood a simple lexical analysis procedure to write complex it is not difficult, is nothing but add a few keywords and writing several conditions judgment statement it. Lexical analysis is the basis of compilers, as well as the most simple. Well, now let us look at the procedures it. Let us look at this small language grammar it

一个简化的编译器，出自美国编译领域的大师劳顿之手，在UNIX/LINUX环境下实现，适合初学者进行分析-a simplified compiler, the United States compiled from the master Lawton hand, UNIX/LINUX environment realized, the analysis for beginners

一个Modula-2语言分析器-A Modula-2 language analyzer

学习简单的Yacc说明的原理，掌握Yacc源文件的写法以及语法分析器生成工具BISON的使用方法和Yacc源文件的运行方法和基本步骤。 -Yacc study shows a simple principle, Yacc master source file written syntax analyzer and generate UML tools and the use of the source language Yacc pieces of the operation and basic steps.

编译原理程序，如有错误请谅解。- Translation principle procedure, if has the mistake please to forgive.

该编译器对表达式可实现词法分析,语法分析,语义分析-The compiler can be realized on the expression of lexical analysis, syntax analysis, semantic analysis
