Description: PL/0语言是Pascal语言的一个子集，我们这里分析的PL/0的编译程序包括了对PL/0语言源程序进行分析处理、编译生成类PCODE代码，并在虚拟机上解释运行生成的类PCODE代码的功能。
PL/0语言编译程序采用以语法分析为核心、一遍扫描的编译方法。词法分析和代码生成作为独立的子程序供语法分析程序调用。语法分析的同时，提供了出错报告和出错恢复的功能。在源程序没有错误编译通过的情况下，调用类PCODE解释程序解释执行生成的类PCODE代码。以下源程序是以清华大学出版社《编译原理》中的源代码为基础作了少量改动而成。
程序在Turbo Pascal 7.0上编译运行通过。
-PL / 0 language Pascal language is a subset of, we have here the analysis of PL / 0 compilers including the right PL / 0 language source analysis, category PCODE compiler code generation and the virtual machine running on to explain the formation PCODE category code functions. PL / 0 language compiler to use syntax analysis of the core, the compiler again scanning methods. Lexical analysis, and code generation as an independent for the subroutine call syntax analysis procedures. Grammatical analysis at the same time, provided a report errors and error recovery functions. The source did not compile the wrong circumstances, PCODE category called to explain the interpretation and implementation of procedures generated PCODE category code. Following is the source Qinghua University Press, &quo

Description: 词法分析器制作与应用
设计思想
(1)程序主体结构部分：
说明部分
％％
规则部分
％％
辅助程序部分
（2）主体结构的说明
在这里说明部分告诉我们使用的LETTER,DIGIT, IDENT(标识符,通常定义为字母开头的字母数字串)和STR(字符串常量,通常定义为双引号括起来的一串字符)是什么意思.这部分也可以包含一些初始化代码.例如用#include来使用标准的头文件和前向说明(forward ，references).这些代码应该再标记"％{"和"％}"之间 规则部分> 可以包括任何你想用来分析的代码 我们这里包括了忽略所有注释中字符的功能,传送ID名称和字符串常量内容到主调函数和main函数的功能.
（3）实现原理
程序中先判断这个句语句中每个单元为关键字、常数、运算符、界符，对与不同的单词符号给出不同编码形式的编码，用以区分之。
PL/0语言的EBNF表示
<常量定义>：：=<标识符>=<无符号整数>
<标识符>：：=<字母>={<字母>|<数字>}
<加法运算符>::=+|-
<乘法运算符>::=*|/
<关系运算符>::==|#|<|<=|>|>=
<字母>::=a|b|…|X|Y|Z
<数字>::=0|1|2|…|8|9-lexical analyzer production and application design (1) procedure main structural elements : narrative%%%% Rules of Procedure supporting part (2) the main structure of the narrative here to tell us so The LETTER, DIGIT, IDENT (identifier, usually defined as the beginning of the alphabet alphanumeric strings) and STR (string constants, usually defined as double quotes name of the string of characters) what it meant. This part also contains some initialization code. cases# include use as to the use of standard documents and the first to the (forward, references). these codes should labeled "% (" and ")%" between some of the rules
