《编译原理实践教程》中的程序作了一些扩展，可以将程序转化成四元式。 本人认为书上的程序极为垃圾！

6个不同的词法语法分析程序源代码，或者说通用c的编译器源码，3个c++控制台程序，3个mfc应用程序，-Six different lexical parsing source code, or common-source compiler c, 3 c++ console process, three mfc application, huh, huh

通信传输系统中的PCM编码解码方式。matlab实现。-Communication System PCM codec mode. matlab achieve.

shpf 1.9一个并行编译器，自动的将串行fortran程序转换成并行的mpi程序。-shpf 1.91 parallel compilers, are automatic transform the serial fortran procedure the parallel mpi procedure.

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.

rs编码和解码功能函数，在网上找到的不少RS编码函数中，这个是比较完整的-rs encoding and decoding function, in-line to find a lot of RS coding function, this is a relatively complete

这是一个编译递归子程序，通过输入语句可以判断是否由指定文法推出-This is a recursive routines compiled by the input to determine whether statements can be specified by the grammar launched
