这个是对上次S语言词法分析的修改,程序已修改好了.

完美反编译各种版本的CHM文件 把所有内容以完整结构(目录路径)反编译出来，100 还原，详细计算各种文件的数量：图片、网页、多媒体等； 支持所有版本的CHM，支持所有编码； 允许有选择性地导出不同类型的文件，包括仅导出所有图片、仅导出所有网页文件、仅导出所有多媒体文件、仅导出列表等； 特有树形结构预览； 支持快速批量反编译，如果导出目标文件夹存在，则会自动生成新的序列文件夹； 智能操作，无所不在的快捷方式与体贴的操作与提示； 自动识别文件类型，判断有潜在威胁的文件类型自动提示！ -Perfect Anti-compiled versions of CHM files Put all the contents of a complete structure (directory path) anti-compiled, 100 reduction, detailed calculation of the number of various documents: images, web pages, multimedia, etc. Supports all versions of the CHM, to support all coding Allow selective export of different types of documents, including the only export all the pictures, only to export all pages of documents, only to export all the multimedia files, only to export the list and so on Special preview of tree structure Support for fast batch decompile, if the export destination folder exists, it will automatically generate a new sequence of folders Intelligence operation, the ubiquitous shortcu

语法分析的功能： 语法分析是编译过程的核心部分，它的主要任务是按照和程序语言的语法规则，从由词法分析输出的源程序符号串中识别出各类语法分析成分，同时进行语法检查，为语义分析和代码生成作准备。 有报告-Parsing functions: syntax analysis is the core of the compiler process, its main tasks and procedures in accordance with the grammatical rules of language, from the output by the lexical analysis of source symbols to identify all types of string parsing components, at the same time syntax checker for semantic analysis and code generation to make preparations. There are reports
