BS ISO/IEC 10514-3:1998

This standard BS ISO/IEC 10514-3:1998 Information technology. Programming languages is classified in these ICS categories:

• 35.060 Languages used in information technology

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).

1.2Specifications 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.
