CSA ISO/IEC 13211-2:02 (R2021)
Standards development within the Information Technology sector is harmonized with international standards development. Through the CSA Technical Committee on Information Technology (TCIT), Canadians serve as the Canadian Advisory Committee (CAC) on ISO/IEC Joint Technical Committee 1 on Information Technology (ISO/IEC JTC1) for the Standards Council of Canada (SCC), the ISO member body for Canada and sponsor of the Canadian National Committee of the IEC. Also, as a member of the International Telecommunication Union (ITU), Canada participates in the International Telegraph and Telephone Consultative Committee (ITU-T).
This International Standard was reviewed by the CSA TCIT under the jurisdiction of the Strategic Steering Committee on Information Technology and deemed acceptable for use in Canada. (A committee membership list is available on request from the CSA Project Manager.) From time to time, ISO/IEC may publish addenda, corrigenda, etc. The CSA TCIT will review these documents for approval and publication. For a listing, refer to the CSA Information Products catalogue or CSA Info Update or contact a CSA Sales representative. This Standard has been formally approved, without modification, by the Technical Committee and has been approved as a National Standard of Canada by the Standards Council of Canada.
This part of ISO/IEC 13211 is designed to promote the applicability and portability of Prolog modules that contain Prolog text complying with the requirements of the Programming Language Prolog as specified in this part of ISO/IEC 13211. This part of ISO/IEC 13211 specifies:
a) The representation of Prolog text that constitutes a Prolog module
b) The constraints that shall be satisfied to prepare Prolog modules for execution, and
c) The requirements, restrictions and limits imposed on a conforming Prolog processor that processes modules.
This part of ISO/IEC 13211 does not specify:
a) The size or number of Prolog modules that will exceed the capacity of any specific data processing system or language processor, or the actions to be taken when the limit is exceeded
b) The methods of activating the Prolog processor or the set of commands used to control the environment in which Prolog modules are prepared for execution
c) The mechanisms by which Prolog modules are loaded
d) The relationship between Prolog modules and the processor-specific file system.
Notes in this part of ISO/IEC 13211 have no effect on the language, Prolog text, module text or Prolog processors that are defined as conforming to this part of ISO/IEC 13211. Reasons for including a note include:
a) Cross references to other clauses and subclauses of this part of ISO/IEC 13211 in order to help readers find their way around
b) Warnings when a built-in predicate as defined in this part of ISO/IEC 13211 has a different meaning in some existing implementations.
