编译原理中间目标代码综合，识别程序，包含语法词法，输出四元组和目标代码-Compiler theory of intermediate target code, identification procedures, including the lexical and syntax, four output tuples and object code

PL/0编译器，识别、分析特定的词法和语法，将源程序编译为类pcode进而生成目标程序并执行(The PL/0 compiler, which identifies, analyzes specific words and syntax, compiles the source program into a class pcode and then generates the target program and executes.)
