标准摘要
[中文适用范围]： 尽管在源程序和语义级别上基本上向上兼容，但定义的语言与以前的 PL/I 标准的语言不同。 附录 A 总结了这些差异。 指定符合 PL/I 程序的语法和语义。 仅根据那些一致的程序定义一致的处理器（或一致的实现）。 该定义是通过指定翻译和解释预期 PL/I 程序的概念 PL/I 机器来完成的。 [外文原描述]： The language defined is different from those of previous PL/I standards, although substantially upward compatible, at the source program and semantic level. The differences are summarized in appendix A. Specifies the syntax and semantics of conforming PL/I programs. Defines a conforming processor (or conforming implementation) only in terms of those conforming programs. The definition is accomplished by specifying a conceptual PL/I machine which translates and interprets intended PL/I programs.
