一个读单词过程，从输入的源程序中，识别出各个具有独立意义的单词，即基本保留字、标识符、常数、运算符、分隔符五大类。并依次输出各个单词的内部编码及单词符号自身值。（-read a word process, from the import of the source to identify all the independent significance of the word, that is to retain the basic character identifier, constant, Operators, separated top-five.

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，如果你做一个新的DFA，就能分析新的词法。 DFA 的初始化在CAjaxParserDlg::OnInitDialog。- Lexical analysis procedure. The core function is condition cut function CAjaxParserDlg::Route. The condition cut function solution acts according to DFA to come to the input text to carry on the analysis. In other words, if you make new DFA, can analyze the new morphology. DFA initialization in CAjaxParserDlg::OnInitDialog.

Grammatica is a C# and Java parser generator (compiler compiler). It improves upon simlar tools (like yacc and ANTLR) by creating well-commented and readable source code, by having automatic error recovery and detailed error messages, and by support for testing and debugging grammars without generating source code. It supports LL(k) grammars with an unlimited number of look-ahead tokens.
