词法分析的程序。核心函数是一个状态切换的函数 CAjaxParserDlg::Route。状态切换函数解根据一个 DFA 来对输入的文本进行分析。也就是说，如果

（1） 给定一段符合Pascal子集语法的语言，能成功转换成C语言； （2） 一个简单的说明文档； （3） 2007.7.14之前上传到ftp:// C07:C07@10.11.3.71/upload,用学号建立自己的目录； （4） （可额外加分5分）若有出错处理功能，请在说明文档中写明可以处理哪几项错误。 注意事项： （1） 两人一组 （2） 可以使用词法、语法自动生成工具，windows下有Flex，Bison，Linux下有Lex，Yacc，Java的有Jlex，JavaCC，ANTLR等 （3） 不用考虑Pascal和C的关键词不同问题，即Pascal子集语言中假设不出现int，for等作为变量标志符 （4） read()和write()可用由scanf()，printf()等组成的语句转换。 （5） 如果有疑问可以发信给我 xpqiu@fudan.edu.cn.

一般的FOrtran程序编译器只能检查一般的错误，而这个软件可以起到一般编译器不能起到的错误检查、程序优化作用。-Ftnchek (short for Fortran checker) is designed to detect certain errors in a Fortran program that a compiler usually does not. Ftnchek is not primarily intended to detect syntax errors. Its purpose is to assist the user in finding semantic errors. Semantic errors are legal in the Fortran language but are wasteful or may cause incorrect operation. For example, variables which are never used may indicate some omission in the program uninitialized variables contain garbage which may cause incorrect results to be calculated and variables which are not declared may not have the intended type. Ftnchek is written in C. To build ftnchek, you must have a C compiler for the machine on which you wish to build it. The URL for ftnchek s home page is http://www.dsm.fordham.edu/~ftnchek. Source code, binary executables for some platforms, and other information are available there.
