ISO/IEC JTC 1/SC 22 Programming languages, their environments and system software interfaces is a standardization subcommittee of the joint technical committee ISO/IEC JTC 1 of the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC), that develops and facilitates standards within the fields of programming languages, their environments and system software interfaces. ISO/IEC JTC 1/SC 22 is also sometimes referred to as the "portability subcommittee". The international secretariat of ISO/IEC JTC 1/SC 22 is the American National Standards Institute (ANSI), located in the United States.
ISO/IEC JTC 1/SC 22 was created in 1985, with the intention of creating a JTC 1 subcommittee that would address standardization within the field of programming languages, their environments and system software interfaces. Before the creation of ISO/IEC JTC 1/SC 22, programming language standardization was addressed by ISO TC 97/SC 5. Many of the original working groups of ISO/IEC JTC 1/SC 22 were inherited from a number of the working groups of ISO TC 97/SC 5 during its reorganization, including ISO/IEC JTC 1/SC 22/WG 2 – Pascal (originally ISO TC 97/SC 5/WG 4), ISO/IEC JTC 1/SC 22/WG 4 – COBOL (originally ISO TC 97/SC 5/ WG 8), and ISO/IEC JTC 1/SC 22/WG 5 – Fortran (originally ISO TC 97/SC 5/WG 9). Since then, ISO/IEC JTC 1/SC 22 has created and disbanded many of its working groups in response to the changing standardization needs of programming languages, their environments and system software interfaces.
Scope and mission
The scope of ISO/IEC JTC 1/SC 22 is the standardization of programming languages (such as COBOL, Fortran, Ada, C, C++, and Prolog), their environments (such as POSIX), and systems software interfaces, such as:
- Specification techniques
- Common facilities and interfaces
The scope of ISO/IEC JTC 1/SC 22 does not include specialized languages or environments within the program of work of other subcommittees or technical committees.
The mission of ISO/IEC JTC 1/SC 22 is to improve portability of applications, productivity and mobility of programmers, and compatibility of applications over time within high level programming environments. The three main goals of ISO/IEC JTC 1/SC 22 are:
- To support the current global investment in software applications through programming languages standardization
- To improve programming language standardization based on previous specification experience in the field
- To respond to emerging technological opportunities
Although ISO/IEC JTC 1/SC 22 has a total of 23 working groups (WGs), many have been disbanded when the focus of the working group was no longer applicable to the current standardization needs. ISO/IEC JTC 1/SC 22 is currently made up of seven active working groups, each of which carries out specific tasks in standards development within the field of programming languages, their environments and system software interfaces. The focus of each working group is described in the group’s terms of reference. Working groups of ISO/IEC JTC 1/SC 22 are:
