SUBMITTED BY: Dr John Reid (Convener of ISO/IEC JTC1/SC22/WG5) JKR Associates, 24 Oxford Road, Benson, Wallingford, Oxon OX10 6LX, UK.

In accordance with WG5's agreed strategic policy, the development of the draft standard was delegated to NCITS/J3, acting as WG5's Primary Development Body. The target date for J3 to deliver the draft standard to WG5 is June 2002. It is expected that the first CD ballot will commence in October 2002. The target date for the publication of the revised standard is December 2004. WG5 and J3 have developed new procedures to provide more effective means for WG5 members to contribute to the work of its Primary Development Body in order to ensure that corrigenda to IS 1539-1:1997 are published in a timely fashion and before the first CD Ballot for Fortran 2000. These new procedures involve WG5 members preparing draft responses at WG5 meetings and my email ahead of J3 meetings at which they are considered further. The first corrigendum was published on 28 June 2001. The second will be submitted for SC22 balloting this autumn. A third may be needed next year. 22.02.03 Programming Language Fortran - Part 3: Conditional Compilation Defect processing has been started and suggested edits are in document WG5 N1409, which was prepared at the meeting in Oulu (August 2000) and will be the subject of an informal letter ballot of WG5 members. All changes are minor except for the omission of a line of text between the DIS and IS. The ISO secretariat agreed to reprint the document with the line restored (see above). It is proposed not to prepare a corrigendum unless other serious defects are found, in which case the changes in N1409 will be included. 1.2.3 Cancelled Projects None. 1.3 Cooperation and Competition WG5 cooperates closely with the ANSI NCITS/J3 Fortran Technical Committee, to whom it has delegated the technical development of Fortran 2000 as well as the maintenance of Fortran 95 (ISO/IEC 1539-1:1997). There is also close contact with the industry-driven HPF and OpenMP Consortia, with several members of the Consortia also being members of J3 and/or WG5. Many of those responsible for the development of commercial Fortran compilers are members of J3 and/or WG5. Other important liaisons are those with IFIP WG2.5 (Numerical Software) and ISO/IEC JTC1/SC22/WG20 (Internationalization). There are no competitive activities. 2 PERIOD REVIEW 2.1 Market Requirements Fortran is still the language of choice for the majority of scientific and technological programming. The long delay between the release of Fortran 77 and the availability of Fortran 90 compilers, at a time when other languages, such as C and C++, were evolving rapidly, had a significant impact on the use of Fortran, but there are now clear signs that the facilities available in Fortran 90 and Fortran 95 are causing a growing number of scientific and technological users to move towards these latest versions of Fortran. Most vendors have upgraded their Fortran 90 compilers to Fortran 95 and some have incorporated the extensions of TR 15580 and TR 15581. Most major Fortran compiler vendors are represented either on WG5 or its Primary Development Body, NCITS/J3, as are many of the major research establishments that rely on Fortran for their numerical computing. There are also two active email lists for users of Fortran, which provide valuable feedback from users. All these diverse sources are being used to guide the development of the language, both through revisions to the base language Standard, and through other related standards and technical reports. 2.2 Achievements Revisions of the Technical Reports TR15580 and TR15581, describing features that will be incorporated in the next revision of the Base Language Standard (Part 1), were published during the year. The first corrigendum to the Base Language Standard was published during the year and processing for the second corrigendum is well advanced. Development work on the next draft of the Fortran standard is complete and integration is in hand. 2.3 Resources As elsewhere in the Standardization world, it is becoming increasingly difficult to persuade employers to provide the necessary funding for Standards activity. WG5 delegates most of the technical work involved in developing Standards and Technical Reports to 'development bodies' which are either based on a national Fortran committee, as in the case of NCITS/J3 - the primary development body responsible for development of the revision to the base language standard and its subsequent maintenance, or consist of a (small) multinational group under the leadership of the relevant project editor. WG5 currently has one such active development body, the primary development body, developing standards, and four development bodies monitoring published standards and technical reports for maintenance purposes. WG5 itself carries out much of its discussions via email, with an annual meeting during the summer, and occasional other meetings at critical stages in the development of the base language standard. The meeting in July/August 2001 was attended by thirteen members, including the Convener, representing six countries. 3 FOCUS FOR NEXT WORK PERIOD 3.1 Deliverables It is anticipated that the second corrigendum for Part 1 of the Standard will be ready for SC22 processing before the end of the year. 3.2 Strategies WG5 operates under a strategic plan described in WG5 Standing Document 4, the latest version of which is WG5 N1349. In particular, the revision of the base Standard, IS 1539-1, is delegated to ANSI NCITS/J3 operating as WG5's Primary Development Body, while the other projects for which WG5 is responsible are handled by other Development Bodies which liaise with the Primary Development Body as required. 3.2.1 Risks As far as possible, WG5 tries to anticipate technical comments during international ballots by holding informal ballots of its members before any documents are submitted for ballot. Nevertheless, unexpected technical comments can always delay the planned schedule. 3.2.2 Opportunities WG5 has made extensive use of email for over a decade to speed up technical development. Since 1995 most documents have been distributed via an official file server in the UK; all documents have been distributed in this way since 1997. An open web site is also used to provide non-technical, and other publicly available, information to interested parties. In addition to speeding up the distribution of documents, the use of electronic distribution and communication systems also provides many other benefits, such as the ability to rapidly carry out informal ballots of the members for various reasons. 3.3 Work Program Priorities Finalization of Corrigendum 2 to Fortran 95 is a WG5 priority activity this year. WG5 members will also monitor, and/or participate in, the work of WG5's Primary Development Body, NCITS/J3, as it moves into the final stages of the development of the Working Draft of the revision of the base Fortran language Standard, ISO/IEC 1539-1:1997. It is intended that this work will reach the CD stage by September 2002. 4 OTHER ITEMS 4.1 Action Requested at the Forthcoming SC22 Plenary WG5 requests that a work item be established for a Type 2 Technical Report on Enhanced Module Facilities with Project Editor Van Snyder and targeted for final publication in 2004/5. 4.2 Recent Meetings 2000/8/14-18 Oulu, Finland 2001/7/30-8/3 London, UK 4.3 Future Meetings 2002/08/11-16 Las Vegas, USA 2003/03/30-04/4 Las Vegas, USA (1st CD ballot resolution) 2003/08 Dresden, Germany 2004/04 USA (Final CD ballot resolution) Note that WG5 normally meets annually, with extra meetings being held as/when necessary to process ballot comments or other high priority activities that do not accord with the regular meeting schedule. WG5's Primary Development Body, NCITS/J3, meets quarterly. Other work is carried out via email.
