Scope

1 This part of ISO/IEC 1539 specifies 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 efficient execution of Fortran programs for use on a variety of computing systems.

2 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.

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

4 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,





    •  
  •  
  •  
  • the maximum number of images, or the size or complexity of a program and its data that will exceed the capacity of any particular computing system or the capability of a particular processor,





    •  
  •  
  •  
  • the mechanism for determining the number of images of a program,





    •  
  •  
  •  
  • the physical properties of an image or the relationship between images and the computational elements of a computing system,





    •  
  •  
  •  
  • the physical properties of the representation of quantities and the method of rounding,





    •  
  •  
  •  
  • approximating, or computing numeric values on a particular processor, except by reference to the IEEE International Standard under conditions specified in Clause 14,





    •  
  •  
  •  
  • the physical properties of input/output records, files, and units, or





    •  
  •  
  •  
  • the physical properties and implementation of storage
