CSA ISO/IEC 8652:25

CSA Preface 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 SCC Mirror Committee (SMC) 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. For brevity, this Standard will be referred to as "CSA ISO/IEC 8652" throughout. This Standard supersedes CSA ISO/IEC 8652:15 (adopted ISO/IEC 8652:2012). The International Standard was reviewed by the CSA TCIT under the jurisdiction of the CSA Strategic Steering Committee on Information and Communications Technology and deemed acceptable for use in Canada. This Standard has been formally approved, without modification, by the Technical Committee and has been developed in compliance with Standards Council of Canada requirements for National Standards of Canada. It has been published as a National Standard of Canada by CSA Group. Scope This document specifies the form and meaning of programs written in Ada. Its purpose is to promote the portability of Ada programs to a variety of computing systems. This document specifies: — The form of a program written in Ada; — The effect of translating and executing such a program; — The manner in which program units can be combined to form Ada programs; — The language-defined library units that a conforming implementation is required to supply; — The permissible variations in conformance to the rules of this document, and the manner in which they are to be documented; — Those violations of the requirements of this document that a conforming implementation is required to detect, and the effect of attempting to translate or execute a program containing such violations; — Those violations of the requirements of this document that a conforming implementation is not required to detect. This document does not specify: — The means whereby a program written in Ada is transformed into object code executable by a processor; — The means whereby translation or execution of programs is invoked and the executing units are controlled; — The size or speed of the object code, or the relative execution speed of different language constructs; — The form or contents of any listings produced by implementations; in particular, the form or contents of error or warning messages; — The effect of unspecified execution; — The size of a program or program unit that will exceed the capacity of a particular conforming implementation.
