4.13 WG21 C++
Convener T. Plum (USA) (1999 - N3013)
ToR Coordinate the development of an ISO standard for programming language C+
Programming language standardization has a long history in the use of character sets in data and in the language itself (e.g. identifiers, literals, etc…)
It is therefore not surprising that the rapid development
and application of ISO/IEC 10646
(code point equivalent to The Unicode Standard) has profound impact on the programming language standards and system interfaces. Many programming language committees are in the process of updating their widely used standards to enable the use of 10646 characters – C, C++, and COBOL are some highly visible examples.
The programming languages C and C++ have specific problem of support for a UTF-16 datatype, and particularly, UTF-16 string literals. This is a problem, because the C/C++ approach of native strings as byte strings, plus wchar_t, lends itself to UTF-8/UTF-32 support (as for many versions of UNIX), but leaves UTF-16 “in the cold”.
SC22/WG20, the working group for internationalization, has
re-issued the TR 10176 – Guide for the development of programming language
standards. Major part of the new TR is
the table in Annex A that defines, which characters a programming language
ought to allow in identifiers to synchronize the recommendation with Unicode
The current TR recommends a wide range of characters form ISO/IEC 10646, the next revision of the TR will ensure that the rapidly expanding repertoire of 10646 characters is adequately represented in Annex A.
An other issue, similarly tied to the repertoire and the architecture of ISO/IEC 10646, needs to solve the problem of equivalence of characters without regard of their case. Again, SC22/WG20 is currently providing such information for the consistent use in programming language standards and an attempt is being made to ensure that the WG20-provided tables are synchronized with the case tables widely available from the Unicode Consortium.
The character set issue, especially in connection with the repertoire of ISO/IEC 10646 and the UTF-16 data type is so dramatic in SC22, that the plenary decided to have a character set ad-hoc during its next meeting in Finland in September of 2002. (see 01-33 in the attached resolutions). As liaison between SC22 and SC2, I urge SC2 to ensure proper support for this planned SC22 character set ad-hoc in 2002.
SC22/WG20 is a member of CLAUI, the JTC1 Technical Direction about Cultural and Linguistic Adaptability and User Interfaces. WG20 has invited the other members of this TD (SC2, SC35) twice, to their May 2001 and October 2001 respectively. Based on the fact that not a single contribution to the meeting had been submitted from any source, WG20 canceled the meeting both times. Contributing to this decision was also the economically stressed situation of the IT industry which has significantly restricted travel.
See resolution 01-24. The future of WG20 is subject of a letter ballot in SC22. Chances are that the maintenance work of WG20 standards and technical reports will be transferred to SC22 if WG20 itself is discontinued.
Resolutions Prepared at the Fourteenth Plenary Meeting of
ISO/IEC JTC 1/SC22
Kona, Hawaii, USA
Resolution 01-00: Special Sympathy and Appreciations
JTC 1/SC22 expresses deep sympathy to all those affected by the tragic events of September 11, 2001.
JTC 1/SC22 expresses special appreciation to the organizers of this plenary, who, despite extraordinary circumstances, have made it successful.
Resolution 01-01: New Work Item for Approval Ballot – TR (Type 2) on Enhanced Facilities in Fortran
JTC 1/SC22 instructs its Secretariat to circulate the proposed New Work Item contained in document SC 22 N3287, Technical Report of Type 2 on Enhanced Module Facilities in Fortran, to SC22 National Bodies for a three-month approval letter ballot.
Resolution 01-02: Retention of Project Not Reaching CD Stage Within Three Years of NP Approval: JTC 1.22.34 - Complex Floating Point Arithmetic and Complex Elementary Numeric Functions
JTC 1/SC22 notes that project JTC 1.22.34, Complex Floating Point Arithmetic and Complex Elementary Numeric Functions, is currently under CD registration ballot per document SC22 N3270. This letter ballot closes 2001-10-26.
Therefore, SC22 requests JTC 1 to extend the time permitted for proceeding to CD stage for Project JTC 1.22.34.
Resolution 01-03: Cancellation of Project Not Reaching CD Stage Within Three Years of NP Approval - JTC1.22.15436 - Interfacing Modula-2 to C
JTC 1/SC22 notes that project JTC 1.22.15436 - Interfacing Modula-2 to C - has exceeded the statutory time for proceeding from NP to CD Stage.
SC22 notes that per Nara Resolution 00-18, this project was granted a one year extension to proceed to CD stage.
Since WG13 has requested the cancellation of this project per SC 22 N3296, SC22 instructs its Secretariat to cancel this project and remove it from the SC22 programme of work, pending JTC 1 approval.
Resolution 01-04: Freely Available Technical Corrigendum for ISO/IEC 9899:1999 (C Language)
JTC 1/SC22 instructs its Secretariat to issue a letter ballot on the following:
JTC 1/SC22 endorses the request from WG14 in SC22 N3289 that Technical Corrigendum 1 to ISO/IEC 9899:1999, Programming Language C, be made freely available, and directs the SC22 Secretariat to immediately forward this request to JTC 1 along with the rationale shown below.
Rationale: WG14 would like to make the Technical Corrigendum 1 for 9899:1999 publicly available on the WG14 web page. Permission was previously granted to place the two Technical Corrigenda for 9899:1990 on the WG14 web page. WG14 believes the C community would be well served by having the exact text of the Technical Corrigendum 1 publicly available. Like software patches that are publicly available (but the full software is not), this Technical Corrigendum 1 contains only the changes, not the entire C Standard. Already, some ISO members distribute the Technical Corrigendum free of charge. Thus, freely distributing the Technical Corrigendum should cause little or no revenue loss.
Resolution 01-05: Retention of Project Not Reaching FDIS Stage Within Four Years of Reaching CD – JTC 1.22.45 - Z Notation
JTC 1/SC22 notes that Project JTC 1.22.54, ISO/IEC FCD 13568 – Z Notation, has not reached the FDIS stage within four years of having reached the CD stage. SC22 notes, however, that significant progress has been made on the project and there is no reason to suppose that it will not be completed.
Therefore, SC22 requests JTC 1 to extend by another year the time permitted for proceeding from the FCD to the FDIS stage for Project JTC 1.22.45.
Resolution 01-06: Appointment of Project Editors
JTC 1/SC22 approves the following appointments as SC22 Project Editors:
- Mr. Roger Scowen for JTC 1.22.14977 - Syntactic Metalanguage - Extended BNF
- Mr. Frank Farance for JTC 1.22.17 -- ISO/IEC 11404:1996 – Language Independent Datatypes.
Resolution 01-07: Standards for Periodic Review
JTC 1/SC22 recommends to JTC 1 that at the end of their
5-year review period:
- The following standards be confirmed:
ISO/IEC 15145:1997 - FORTH
ISO/IEC 13813:1998 - Ada Complex Functions;
- The following standard be withdrawn:
ISO/IEC 13814:1998 - Generic Package of Complex Elementary
Functions in Ada;
Resolution 01-29: Periodic Review of ISO/IEC 13816 - Programming Language Lisp
JTC 1/SC22 requests a recommendation from the SC22/WG16 Convenor as to whether ISO/IEC 13816 should be confirmed, revised, or withdrawn as part of the JTC1 Five Year Review and instructs its Secretariat to issue an appropriate Letter Ballot.
Resolution 01-30: Periodic Review List for 2003
JTC 1/SC22 instructs all SC22 WGs to review N3222 and provide written recommendations prior
to the 2002 SC22 Plenary for all of their standards that are included on the
Five-Year Review list for 2003.
Resolution 01-08: New Work Item for Approval Ballot - TR (Type 2) on C++ Library Extensions
JTC 1/SC22 instructs its Secretariat to circulate the proposed New Work Item contained in document SC 22 N3277, Technical Report of Type 2 on C++ Library Extensions (based on ISO/IEC 14882), to SC22 National Bodies for a three-month Approval Letter Ballot.
Resolution 01-09: Call for Candidates for PCTE Project Editor
JTC 1/SC22 instructs its Secretariat to conduct a call for candidates to serve as PCTE (JTC 1.22.47) Project Editor. If an individual is not identified, this position will be canceled.
Resolution 01-10: Letter Ballot for Freely Available Technical Report - ISO/IEC 15942 Guidance for Use of Ada In High Integrity Systems (Type 3 TR)
JTC 1/SC22 instructs its Secretariat to issue a letter ballot on the following:
ISO/IEC JTC 1/SC22 endorses the request from WG9 in SC22 N3256 that ISO/IEC TR 15942, Guidance for Use of Ada In High Integrity Systems (Type 3 TR), be made freely available, and directs the SC22 Secretariat to immediately forward this request to ISO/IEC JTC 1 along with the rationale shown below.
Rationale: TR 15942 qualifies under the criteria provided by JTC 1 Sendai Resolution 32 because it is a Technical Report. It also qualifies under the criteria of JTC1 N 5165 because it explains inter-relationships among the referenced standards and thereby serves to promote the work of JTC1 possibly leading to increased sales of the referenced standards.
Resolution 01-11: Re-appointment of Working Group 15 Convener
JTC 1/SC22 approves the re-appointment of Mr. Jim Oblinger as Convener of WG15 – POSIX.
Resolution 01-12: ISO/IEC JTC 1/SC22 Plenary for 2002
JTC 1/SC22 thanks the Finnish Member Body for its generous offer to host the JTC 1/SC22 2002 Plenary in Saariselkä, Finland beginning 26 August 2002 and is pleased to accept the offer.
Resolution 01-13: Retention of Project Not Progressing for Three Years or
More - JTC 1.22.15879 – Distributed Software Administration DCE-RPC Interoperability (XDSA/DCE)
Per SC 22 N3272, project JTC 1.22.15879, ISO/IEC DIS 15879, Distributed
Software Administration DCE-RPC Interoperability (XDSA/DCE), has not progressed for three years or more (DIS stage since 1998-02-24).
JTC 1/SC22 instructs the WG15 Convener to contact Mr. M. Kirk of the PAS submitter, The Open Group, to request a status report on this project and recommendation for further action. (Note: Resolution 01-15 requests an extension of one year for this project.)
Resolution 01-14: Withdrawal of Projects
At the recommendation of WG15 (SC22 N3315), JTC 1/SC22
instructs its Secretariat to withdraw the following projects, pending JTC 1
1. JTC 1.22.21.03.01, 15068-1, System Administration Overview
2. JTC 1.22.21.01.03.03, PDAM 4 to 9945-1, Amendment 4 to Portable Operating System Interface (POSIX) - Part 1: System API

Resolution 01-18: Letter Ballot - Establishment of Liaison with IETF
In response to the request from WG20 (N3284) to establish a liaison with IETF, JTC 1/SC22 instructs its Secretariat to issue an SC22 Letter Ballot on the following:
The Internet Engineering Task Force has requested a Category A liaison with ISO/IEC/JTC1/SC22. The Rationale for this request is contained in document N3284. ISO/IEC/JTC1/SC22 agrees instead to offer IETF a category C liaison with ISO/IEC/JTC1/SC22.
Resolution 01-18a: Request for appointment of JTC1 Coordinating Officer
Noting that IETF currently has liaisons with SC2, SC6, and SC27, JTC 1/SC22 requests that JTC 1 appoint Mr. Doug Johnson as JTC1 Coordinating Officer for its IETF liaisons (see Resolution 01-18 and JTC1 Directives 220.127.116.11).
Resolution 01-19: Future of WG13
In response to N3296 (SC 22/WG13 Report), JTC 1/SC22 requests its chairman to communicate with Mr. Martin Schoenhacker (WG13 [Modula-2] convenor) that there is no provision in the procedures to continue a WG as a maintenance body. Therefore, the WG must be officially disbanded if there is no additional development work envisioned.
