《PL/0的编译器》：PL/0语言是Pascal语言的一个子集，《PL/0的编译器》实现了把客户用PL/0语言编写的程序编译成类PCODE代码，并能虚拟机上解释运行生成的类PCODE代码的功能。《PL/0的编译器》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。-"PL / 0 compiler" : PL / 0 Pascal language is a language subset, "PL / 0 compiler" achieved the customers using PL / 0 language procedures compiled PCODE category code and the virtual machine can explain the operation generated PCODE category code functions. "PL / 0 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 program. Grammatical analysis at the same time, provided a report errors and error recovery functions.
