Committee ISO/IEC JTC 1/SC 22 (abbreviated as SC 22) oversees the standards for programming languages and environments, that have been published jointly by ISO (www.iso.ch) and IEC (www.iec.ch). SC 22 meets at an annual Plenary to review the progress of its work. This year’s meeting was held in Delft, the Netherlands, on September 31 and October 1. The Chair of SC 22 is Rex Jaeschke (rex@RexJaeschke.com). Plenary attendees are delegates authorized by National Body (NB) members.
The technical work of SC 22 is done by its Working Groups (WGs), which are, as follows:
- WG4 – COBOL
- WG5 – Fortran
- WG9 – Ada
- WG11 – Binding Techniques
- WG14 – C
- WG16 – ISLisp
- WG17 – Prolog
- WG19 – Formal Specification Languages
- WG21 – C++
- WG23 – Programming Language Vulnerabilities
Standards developed outside SC 22, but submitted to it via some external process, and published by ISO and IEC, include the languages C#, ECMAScript, Forth, and Mumps/M, and the platforms CLI (a subset of Microsoft’s .NET), Linux Standards Base, and POSIX.
