词法分析器

本文主要介绍了GPJPascal编译器的构造，其中，词法分析器扫描源程序，根据语言的词法规则，分解和识别出每个单词，同时进行词法检查；

In the paper , the structure of the GPJ_Pascal compiler is mainly introduced , the lexer can scan the source program according to the morphology rule of language which can decompose and distinguish every word , and carry out morphology inspection at the same time ;
