1.1目标 除了Base语言的目标外，ISO/IEC 10514这一部分的目标是 提供简单的扩展以允许将面向对象编程工具添加到 国际标准ISO/IEC 10514-1中定义的基本语言 基语言允许的任何有效程序的含义（除了使用新的 本标准引入的关键词，见第5条）。 1.2 ISO/IEC 10514本部分包含的规范 除了基本语言中包含的规范之外，ISO/IEC 10514的这一部分 提供以下规格: -面向对象Modula-2程序所需的符号； -面向对象模块-2的词法结构、句法结构和语义 程序； -面向对象模块的接口和语义-2个系统模块； -违反使用符合的面向对象扩展的规则 需要实现来检测； -实施的进一步合规要求，包括文件 要求。 1.3与ISO/IEC 10514-1的关系 ISO/IEC 10514的这一部分是多部分标准ISO/IEC 10514的第三部分。这部分 ISO/IEC 10514扩展和修改了基本语言ISO/IEC 10514-1，但是 对于基本语言，采用ISO/IEC 10514的这一部分是可选的。这个 ISO/IEC 10514的一部分也独立于ISO/IEC 10514的任何其他部分，除了 并且可以与这些其他部分一起或独立地采用。 1.4不在ISO/IEC 10514本部分范围内的规范 除了基础语言排除的规范类别之外，这部分 ISO/IEC 10514未提供以下方面的规范: -对象及其相关方法的内部表示； -垃圾收集器的实现； -对被跟踪对象的跟踪机制的实现。

1.1 Goals In addition to the goals of the Base Language, the goal of this part of ISO/IEC 10514 is to provide simple extensions to allow object oriented programming facilities to be added to the Base Language defined in International Standard ISO/IEC 10514-1 without altering the meaning of any valid program allowed by the Base Language (except for the use of the new keywords introduced by this standard, see clause 5). 1.2 Specifications included in this part of ISO/IEC 10514 In addition to the specifications included in the Base Language this part of ISO/IEC 10514 provides specifications for: — required symbols for Object Oriented Modula-2 programs; — the lexical structure, the syntactic structure and semantics of Object Oriented Modula-2 programs; — the interface to and the semantics of Object Oriented Modula-2 system modules; — violations of the rules for the use of the object oriented extensions that a conforming implementation is required to detect; — further compliance requirements for implementations, including documentation requirements. 1.3 Relationship to ISO/IEC 10514-1 This part of ISO/IEC 10514 is part three of the multi-part standard ISO/IEC 10514. This part of ISO/IEC 10514 extends and modifies the Base Language ISO/IEC 10514-1, but the adoption of this part of ISO/IEC 10514 is optional with respect to the Base Language. This part of ISO/IEC 10514 is also independent of any other parts of ISO/IEC 10514 except for part 1, and can be adopted either together with or independently of such other parts. 1.4 Specifications not within the scope of this part of ISO/IEC 10514 In addition to the categories of specifications excluded by the Base Language this part of ISO/IEC 10514 provides no specifications for: — the internal representation of the objects and their associated methods; — the implementation of the garbage collector; — the implementation of the tracking mechanism for traced objects.
