拿出这个程序来主要是因为原文中只有一个LEX程序,

Full support for extended regular expressions (those with intersection and complement); Support for some kinds of cycles in grammar; DFA-based operation; Unicode support; C++ only, requires a modern compiler; Lexical analyzers can be configured to get symbols from any input class (built-in support for std::istream, std::wistream and FILE *); Designed to work with Whale, but can work standalone or interface to other parsers.-Full support for extended regular expressions (those with intersection and complement); Support for some kinds of cycles in grammar; DFA-based operation; Unicode support; C only, requires a modern compiler; Lexical analyzers can be configured to get symbols from any input class (built-in support for std::istream, std::wistream and FILE*); Designed to work with Whale, but can work standalone or interface to other parsers.

Fenris是一个检测并把高层次的语言结构做成文档的多功能故障检测器、调试器、代码分析工具。它能回复符号，把程序执行流绘成图，检查内部运行情况，恢复符号表，并处理反调试保护。它有一个命令行接口和一个类似SoftICE的GUI与Web前端-Fenris is a detection and high-level language structure made of multifunctional document fault detection, debugging, code analysis tools. It can restore symbols, compose program execution flow map, check their internal operations, restoration of the symbol table, and to deal with anti-debugging protection. It is a command line interface and a similar SoftICE with the GUI front-end Web

JC1.0。本编译器包含完整的文档与程序。借助 Lex & Bison, masm 开发。语句5个，支持混合运算。输入输出作为两个 IO 语句（函数调用），由汇编实现并编译为 io.obj，将由 Link 链接。生成 EXE。整个流程完整清晰，代码易读。-JC1.0. The compiler includes complete documentation and procedures. With Lex Bison, can develop. Statement 5, support mixed computing. Input and output as two IO statement (function call), compiled by the compiler to achieve and io.obj will link Link. EXE generation. The entire process, complete and clear, legible code.
