1 This part of ISO/IEC 1539 speci es the form and establishes the interpretation of programs expressed in the baseFortran 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.2 This part of ISO/IEC 1539 speci es 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 speci ed by this part of ISO/IEC 1539 apply toprograms 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 interpretationexcept 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 thecapacity 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 ofa computing system, the physical properties of the representation of quantities and the method of rounding, approximating, orcomputing numeric values on a particular processor, except by reference to the IEEE International Standardunder conditions speci ed in Clause 14, the physical properties of input/output records, les, and units, or the physical properties and implementation of storage.
