UK requirements for next revision of Fortran language

Fortran 2003 is expected to be published as a standard later this year and WG5 is preparing to consider requirements for the next revision of the language. Proposals from users go first to the national member body (BSI in the case of the UK) before being forwarded to the ISO committee.

The Fortran Specialist Group is holding a meeting in March 2005 to discuss UK requirements. If you are unable to attend anyone in the UK is invited to make proposals, using the template below. They should be sent to me at the address below before May 2005.
Please use the following headings:

Title:this must be short and informative (it will be used in an index)
References:are ISO standards or SC22, WG5, or J3 paper numbers (may be blank)
Basic Functionality:a short description
Rationale:reasons for standardizing the feature including the expected users of the feature
Estimated Impact:indicates other features that would be affected and explains how they would be affected
Detailed Specification:as much detail as possible should be supplied

Formally, those living outside the UK should submit proposals through their own national standards body. The following are also members of the ISO Programming Languages Committee and had votes on the Fortran FCD: Austria, Belgium, Brazil, Canada, China, Czech Republic, Denmark, Egypt, Finland, France, Germany, Ireland, Italy, Japan, DPR of Korea, Republic of Korea, Netherlands, Norway, Russian Federation, Romania, Slovenia, Switzerland, Ukraine, USA. In addition the following are 'observer' members and are permitted but are not obliged to vote: Argentina, Bulgaria, Cuba, Estonia, Greece, Hungary, Iceland, India, Indonesia, Israel, Kenya, New Zealand, Poland, Serbia and Montenegro, Singapore, Sweden, Thailand, Turkey. A full list of ISO members is available on the ISO web site. However in case of difficulty please send comments to me.

Requirements submitted to date

The requirements submitted for consideration by the BSI panel at the time of writing are:

  • Coarray Fortran, a parallel extension to array processing

  • Decimal floating point arithmetic, an extension to take advantage of coming decimal hardware

  • Conformance to IEEE 754R, also for decimal arithmetic

  • Improved Elemental capability, an extension to relax global parameters temporarily

  • Kind environment specification, an extension to make the kinds implemented in a process more easily accessible to the programmer

It does not necessarily follow that these will all be submitted to WG5 for further processing.
