Annotation

This part of ISO/IEC 1539 speci es the form and establishes the interpretation of programs expressed in the base Fortran language. The purpose of this part of ISO/IEC 1539 is to promote portability, reliability, maintainability, and ecient execution of Fortran programs for use on a variety of computing systems.

This part of ISO/IEC 1539 specifies

• the forms that a program written in the Fortran language may take,

• the rules for interpreting the meaning of a program and its data,

• the form of the input data to be processed by such a program, and

• the form of the output data resulting from the use of such a program.

Except where stated otherwise, requirements and prohibitions specified by this part of ISO/IEC 1539 apply to programs rather than processors.

This part of ISO/IEC 1539 does not specify

• the mechanism by which programs are transformed for use on computing systems,

• the operations required for setup and control of the use of programs on computing systems,

• the method of transcription of programs or their input or output data to or from a storage medium,

• the program and processor behavior when this part of ISO/IEC 1539 fails to establish an interpretation except for the processor detection and reporting requirements in items (2) to (8) of 1.5,
