JTC1/SC22/WG5

Revision of ISO/IEC 1539-1:2004

(Information technology - Programming languages - Fortran)

Fortran 2003 (which is Part 1 of the multi-part Fortran Standard) is a major enhancement of Fortran 95 Standard.

WG5 is currently working on a minor revision of the language, with a target publication date of 2008. The current working draft can be accessed from the J3 file server as standing document 007 in a variety of formats.

It will include the feature defined by the Technical Report:

ISO/IEC TR 19767:2005(E) Enhanced module facilities

whose final draft is visible as N1602. This was written as a Technical Report because the feature was deemed too important to wait for the next revision of the Standard.

The major new features that are planned are:

1. Parallel programming support: SPMD parallel programming using co-arrays for data exchange

2. A BITS data type for non-numeric programming and enhanced handling of binary, octal, and hexadecimal constantsFeatures to allow object oriented programs to be written in Fortran

3. Scoped macros which can generate whole Fortran statements and subprograms

In addition, there are a considerable number of minor technical enhancements.
