1. PL/0 语言介绍
●PL/0 程序设计语言是一个较简单的语言,它以赋值语句为基础,构造概念有顺序、条件和重复(循环)三种。PL/0 有子程序概念,包括过程定义(可以嵌套)与调用且有局部变量说明。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。
●保留字(关键字):所谓保留字是指在Pascal语言中具有特定的含义。标准Pascal语言中的保留字一共有35个,Turbo Pascal语言一共有51个。下面是Pascal语言的保留字:AND,ARRAY,BEGIN,CASE,CONST,DIV,DO,DOWNTO,ELSE,END,FILE,FOR,FUNTION,GOTO,IF,IN,LABEL,MOD,NIL,NOT,OF,OR,PACKED,PROCEDURE,PROGRAM,RECORD,REPEAT,SET,THEN,TO,TYPE,UNTIL,VAR,WHILE,WITH,EXPORTS,SHR,STRING,ASM,OBJECT,UNIT,CONSTRUCTOR,IMPLEMENTATION,DESTRUCTOR,USES,INHERITED,INLINE,INTERFACE,LIBRARY,XOR,SHL
