Fortran Language Features
This is an overview of Fortran 95 language features which is based upon the standards document which has been replaced by a newer version. Included are the additional features of TR-15581:Enhanced Data Type Facilities, which have been universally implemented. Old features that have been superseded by new ones are not described few of those historic features are used in modern programs although most have been retained in the language to maintain backward compatibility. The additional features of subsequent standards, up to Fortran 2023, are described in the Fortran 2023 standard document, ISO/IEC 1539-1:2023. Some of its new features are still being implemented in compilers. Details can also be found in a range of textbooks, for instance and see the list at Fortran Resources. Sources for the description in the sections below can be found in the standards documents, textbooks as well as the Fortran 95 language features#Bibliography, Bibliography.

Backward Compatibility
In telecommunications and computing, backward compatibility (or backwards compatibility) is a property of an operating system, software, real-world product, or technology that allows for interoperability with an older legacy system, or with Input/output, input designed for such a system. Modifying a system in a way that does not allow backward compatibility is sometimes called "wikt:breaking change, breaking" backward compatibility. Such breaking usually incurs various types of costs, such as Switching barriers, switching cost. A complementary concept is ''forward compatibility''; a design that is forward-compatible usually has a Technology roadmap, roadmap for compatibility with future standards and products. Usage In hardware A simple example of both backward and forward compatibility is the introduction of FM broadcasting, FM radio in stereophonic sound, stereo. FM radio was initially monaural, mono, with only one audio channel represented by one signal (electrical engineerin ...
