ISO/IEC JTC1/SC22/WG9 N333 -- 3 July 1997 Minutes of ISO/IEC JTC1/SC22/WG9 Meeting #32 Monday, 2 June 1997 London, UK NOTES * World-Wide Web URLs are enclosed in {curly brackets}. ---------------------------------------------------------------------------- The 32nd meeting of ISO/IEC JTC1/SC22/WG9 (Ada) was held Monday, 2 June 1997, in the Mortimer Room of the Tower Thistle Hotel, London, England, United Kingdom in conjunction with the Ada-Europe'97 conference {http://www.sis.port.ac.uk/adauk/Ada-Europe/Conference/1997/}. ---------------------------------------------------------------------------- Opening Orders Call to Order: Jim Moore, Convener, called the meeting to order at about 9:00 am. Appointment of Meeting Secretary Clyde Roby agreed to serve as Secretary at meeting #32; appreciation was given for this. Approval of Agenda The agenda was distributed and slight changes were made to accommodate the lunch meetings of a few people. Welcome and Administrative Arrangements: John Barnes (UK) Convener thanked Ada-Europe and especially John Barnes for making arrangements for this meeting. Approval of Minutes of Meeting #31 By the following resolution, the minutes of the Philadelphia meeting, available as document N323 {http://www.open-std.org/jtc1/sc22/wg9/documents.html#N323}, were approved as corrected. RESOLUTION: The Minutes of Meeting #31 (N323) are approved with the following corrections: 1. his term will run though August 2000: though -> through 2. contains the Table of Contents, Forward, General, and: Forward -> Foreword 3. between 1.1.96 and 31.11.96: 31 -> 30 (Erhard said 31, but November has 30 days only.) 4. whether technical details of AIs should discussed at WG-9 meetings: should -> should be 5. Tom Plumb has replaced him: Plumb -> Plum ---------------------------------------------------------------------------- Convener's Report Convener's recent report to SC22 can be found at {http://www.open-std.org/jtc1/sc22/wg9/documents.html#N328}. Copyrights of ISO Working Documents The issue of copyrights of ISO working documents was discussed. The reason for copyrights for documents is so that changes are not indiscriminately made to them. In addition, contributions by National Bodies (NBs), though not copyrighted, must be protected. There is currently a one-year trial period during which the requirement to place a copyright notice on WDs and CDs has been suspended. Electronic Distribution of Documents JTC1 and SC22 are rapidly moving toward distributing documents only in electronic form. SC22 will shift totally to electronic document distribution by September 1997. Currently, only about 25 percent of SC22's documents are distributed in paper copy. Revised Procedures for Progress of Documents The progression of documents among JTCs, SCs, and WGs is such that the procedures are now being made more similar. The inquiry phase within NBs must be done at "Final CD ballot". The normal progression of documents is now as follows (this was shown in graph form on a slide, beginning with a Working Draft): * CD registration: Three months in duration. * CD ballot: Three months in duration. Technical comments accepted. May be repeated if necessary. * Final CD ballot: Four months in duration. Last chance for technical comments. May be repeated if necessary. * Final DIS ballot: Two months in duration. No technical comments. Up or down decision. The DIS designation is now only used for fast-track ballots. Role of Language Bindings in SC22 Work Programme From Robert Follett, Chair of SC22 -- Development of a standard for a language binding requires knowledge and expertise in two areas - the standard for the technical subject of the binding and the standard for the programming language involved. Thus, for example, the development of the GKS Fortran binding required expertise in both GKS and Fortran. It has generally been the case in the past that the binding is best produced by experts in the technical subject of the binding rather than by programming language experts. As a result, the language bindings developed in SC 22 have involved bindings to technical areas within SC 22, e.g., POSIX or PCTE, but not to technical areas in other SCs, e.g., graphics bindings in SC24. SC 22 believes this division of work is appropriate. There may be times when a language binding would be produced by the language experts but such cases should be assigned on a case by case basis and are not the general rule. Upcoming SC22 Plenary in Ottawa Convener plans to attend the forthcoming SC22 plenary in Ottawa, 18-22 August 1997. Rapporteur Group chairs are reminded of the following action item: ACTION 31-3 (Rapporteur Group Chairs): WG9 encourages its Rapporteur Groups to schedule their meetings in conjunction with the SC22 plenary in Ottawa, 18-22 August 1997. Each RG chair should correspond with Steve Michell regarding their intentions. Open: RG Chairs are still encouraged to schedule meetings in conjunction with the SC22 plenary meeting. ---------------------------------------------------------------------------- National Body Reports and Introductions The following delegations and individuals attended this meeting; reports given are also included. * Canada: Steve Michell (head), Vincent Celier The SC22 plenary meeting in Ottawa in August was again noted. * France: Jean-Pierre Rosen A meeting was held at AFNOR on 24 May where many of the AIs were discussed. France voted NO on the Numeric standards because the French translation on the title is currently wrong. Convener noted that ISO 12182 is the preferred choice of English/French phrases for translations. * Germany: Erhard Ploedereder, Karlotto Mangold Rudolf Landwehr resigned as Head of Delegation; Erhard substituted as acting Head of Delegation from Germany. * Japan: Kiyoshi Ishihata No report. * Sweden: Bjorn Kallberg No report. * Switzerland: Alfred Strohmeier no report. * United Kingdom: John Barnes, Michael Pickett, Brian Wichmann They responded to ASIS document comments. * United States: Joyce Tokar (Head), Ted Baker, Currie Colket, Robert Dewar, Clyde Roby, Tucker Taft The US will probably constitute a Technical Advisory Group (TAG) for Ada. ---------------------------------------------------------------------------- Scheduling of Meetings #33 and #34 The following resolution was approved. RESOLUTION: Meetings #33 and #34 of ISO/IEC JTC1/SC22/WG9 are scheduled as follows: * Meeting #33: Friday, 14 Nov 1997, with Tri-Ada in St. Louis, Missouri, USA * Meeting #34: Friday, 12 June 1998, with Ada-Europe, Uppsala, Sweden Rapporteur Groups are encouraged to meet in Ottawa, Canada in conjunction with the SC22 Plenary meeting, 18-22 August 1997. The point of contact for arranging meetings is Steve Michell. ---------------------------------------------------------------------------- Electronic Communications and ISO Copyright Policy: Convener JTC1 and SC22 are moving aggressively to eliminate paper distribution of documents and to move toward electronic distribution methods, even for balloting. On the other hand, ISO seeks to impose its copyright upon all products of the standardization product. A one-year trial period has been approved during which the requirement for ISO copyright upon documents below the level of DIS has been suspended. Additional information regarding these changes can be found at a Web site dedicated to this purpose, {http://www.open-std.org/JTC1/IMPIT/} particularly {http://www.open-std.org/JTC1/IMPIT/open/j1n4558/j1n4558.htm}. It was noted that other standards groups are planning to make their documents openly available. JTC1 has indicated that SC22 can make pilot projects to test their procedures. Currie noted that electronic distribution of ASIS related documents has been a necessity; information was provided in electronic form and distributed and used electronically. He made two points: 1. Electronic distribution is indispensable for ASIS, allowing much more participation in the international community. 2. The ASIS specification needs to be distributed electronically as it is a compilable Ada specification needed by ASIS implementors; the copyright policy is an issue for ASISRG. Would the ASIS specification have to be licensed from ISO? Alfred suggested that we ask our Convener to ask the JTC1 Secretariat for clarification/guidance, showing examples as POSIX, GKS (Fortran binding), and the C Template Library. It was noted that the IEEE POSIX group would not allow copying of any of its standards, even with computer language code in them. But they later relented and allowed the distribution of the code. Effects on WG9 participants SC22 adopted a policy concerning formats, thus you should be prepared to read documents in any of the following formats: * Hypertext Markup Language (HTML); * Portable Document Format (PDF); * Plain DOS Text file, encoded in ISO/IEC 8859-13; * Microsoft Word Version 2.0 or higher; * WordPerfect Version 5.1 or higher. * Rich Text Format (RTF) Word is not a suitable mechanism for trading electronic documents. For distributing documents where CONTENTS are important, HTML is a good mechanism. For distributing information where PRESENTATION is more important, PostScript is probably the best. But there are problems with PostScript; it is not totally compatible for all printers. It was noted that PDF may be better than PostScript, but many people have problems in generating PDF. We concluded that we should avoid Word and WordPerfect for standards documents, but not necessarily for informal documents. Also, PostScript is much more platform independent but it is not one of the choices that ISO allows. It was noted that although the ASIS Working Draft is maintained in Microsoft Word, Version 6.0, the document is also available in PostScript, ASCII, RTF, and hopefully soon, HTML. WG9 will continue to use its Web site to make documents available. At some point, we will set up a password-protected Web site also. We are capable of doing this whenever it is desired. For informal documents, HTML and plain ASCII text are preferred methods of distribution. RTF may be preferable to either Word or WordPerfect. Word documents should be designed so that understandability is not hampered by changing page size between 8-1/2 x 11 and A4. The use of the default "Normal" style for text should be avoided. ---------------------------------------------------------------------------- WG9 has been using RGs as standing bodies, but they perform a task and then go away. Convener's policy is to aggressively discharge RGs when their work is complete. Project editors are recognized as officers of JTC1/SC22. Convener will aggressively appoint project editors; project editors maintain a list of technical clarifications and corrections for a document and then develop a Technical Corrigenda at an appropriate time. ---------------------------------------------------------------------------- Report of Project Editor, TR 11735: Nasser Kettani 22.35, TR 11735:1996, Real-time Extensions The Type 2 Technical report was published 14 November 1996. The following resolution was approved. RESOLUTION: Having completed their chartered mission, the Real-Time Rapporteur Group is discharged, as of Meeting #31, with the grateful appreciation of ISO/IEC JTC1/SC22/WG9. The RRG has made important contributions to Ada technology through the drafting of Type 2 Technical Report 11735, describing real-time extensions suitable for use with Ada. ---------------------------------------------------------------------------- Report of Project Editor, IS 12227: Andreas Koeller 22.31, IS 12227:1995, SAMeDL The following resolution was approved. RESOLUTION: Having completed their chartered mission, the SQL Rapporteur Group is discharged with the grateful appreciation of ISO/IEC JTC1/SC22/WG9. The SRG has made important contributions to Ada technology through the drafting of the SAMeDL standard, IS 12227. ---------------------------------------------------------------------------- Report of Ada Rapporteur Group: Erhard Ploedereder, Chair 22.10.01, IS 8652:1995, Ada Programming Language, Project Editors - Chris Anderson and Tucker Taft (US) ADMINISTRATIVE ACTION: Subject to approval by SC22, the convener appointed Erhard Ploedereder and Bob Duff as Project Editors to perform the continuing responsibilities associated with IS 8652:1995. The following resolution was approved. RESOLUTION: ISO/IEC JTC1/SC22/WG9 expresses its grateful appreciation to Chris Anderson and Tucker Taft for their accomplishments as Project Editors of IS 8652:1995. Standard Corrigendum Erhard Ploedereder gave his report on the ARG. The ARG met at Henley and approved a new set of AIs. The AIs presented at the current WG9 meeting reflect the work of the previous ARG meeting. The following resolution was made. RESOLUTION: To approve the following AIs which have been previously approved by the ARG: * AI95-00001 -- Ada.Streams.Stream_IO.Stream can raise Status_Error (10-0-1) * AI95-00012 -- The first subtype of a type defined by an access[_type]_definition (10-0-0) * AI95-00054 -- When is a Small clause allowed? (6-1-0) * AI95-00060 -- No Predefined 'Truncate Attribute on Fixed-Point Types (6-0-1) * AI95-00064 -- Elaboration checks for renamings-as-body (9-0-0) * AI95-00086 -- Passing generic formal packages with (<>) (5-0-2) * AI95-00094 -- Exponentiation: 0.0 ** 0.0 raises Argument_Error. (7-0-0) * AI95-00099 -- Accuracy requirements for elementary functions (6-0-1) * AI95-00123 -- Equality for Composite Types (10-0-2) * AI95-00125 -- Order of Size and Small Clauses for Fixed Point Types (6-0-1) * AI95-00128 -- String Packages (12-0-0) * AI95-00135 -- Circular Renamings as Body (6-0-3) * AI95-00157 -- Visibility of Inherited Private Components (12-0-0) * AI95-00163 -- User-defined fixed,fixed multiplying op (10-0-1) * AI95-00180 -- Pragma Elaborate for Child Units (8-0-2) Jean-Pierre Rosen of France raised an issue concerning AI95-00157 (an editorial correction) and AI95-00163 (for which there was some discussion). No changes were made. The above resolution was approved 8-0-0. Briefing and Discussion of C Interfacing Issues Briefing There are several issues in this area: 1. The problem with the positioning of exceptions in the C.Interfaces packages. This was resolved at the last WG9 meeting. 2. The calling convention for records passed to C routines 3. The rules for the conventions of inherited subprograms 4. Java interfaces modeled in Ada by changing the renaming semantics a little bit. This is interesting but more must be written up. The global question is: how progressive and how (in)compatible can changes be to make Ada more easy to interface with other languages? Calling Conventions At issue is the parameter passing convention for records passed to a subprogram with convention C (AI-131). The RM contains Implementation Advice to use by-reference passing in this case. B.3(69). However, the C standard passes structs by-value. While this Implementation Advice models the C programming idiom to often pass structs by reference, i.e., as t* rather than t, and hence is a convenience in many cases, it also makes it impossible to interface to a C routine that does not adhere to this idiom. The possible actions are: * 1. Confirm the RM. The argument in favor is the "too late for the change" argument, since existing bindings relying on by-reference passing would be affected. * 2. Fix the RM to alter the Advice to by-value passing. The argument in favor is that this matches the C standard and that interfacing to all C routines becomes possible. * 2.a. As an alternative to 2, it has been proposed to advise by-value only for record types with convention C, thus slightly ameliorating the incompatibility. * 3. Follow the action of (at least) two Ada implementations which are providing implementation-defined pragmas to achieve by-value passing of records. In this case, form and semantics of the pragma should be specified. (The "too late" argument applies here as well, since the two implementations are rumored to have different semantics.) The ARG is split on the issue. In Montreux, 2/2a was the preferred alternative, in Vermont opinion swayed to 1, in Henley it received a 2:3:5 vote. Discussion at this meeting included the following salient points. In real terms, this is really a uniformity issue. Should there be Implementation Advice (which is relatively weak)? Action 3.b. was added; it was similar to 3 above, except that the pragma(s) would be specified. There was some discussion about whether or not real Ada bindings should have an access type to the C struct, whether or not it is implemented as call-by-value; but for the quick-and-dirty bindings, we should be compatible with the C language standard. It would remain as Implementation Advice, though. Action 2.b. was added. Make it a Binding Interpretation and reference the C language standard. We finally agreed to a straw vote (for the ARG) on the following two actions: 1. Make call-by-value mandatory (reference the C standard). The individuals present voted 13-1-1. 2. Use mandatory pragma(s). The individuals present voted 6-1-8. The following resolution passed 8-0-0. RESOLUTION: It should be possible to write portable bindings to C programs. The ARG is requested to propose an appropriate mechanism. Rules for the conventions of inherited subprograms At issue are the language rules regarding the convention of dispatching operations. Presently, the rules specify that their calling convention is Ada, unless the convention is specifically overridden. On the other hand, there is the rule that overriding subprogram declarations must have the convention of the overridden subprogram. (With friendly reading of the RM, inherited subprograms inherit the convention of their parent, rather than being always of convention Ada.) If tagged types are interfaced to OOP types in another language, e.g. C++, the imported operations will have to be of convention C++. This leads to two problems: 1. Although there is no choice on the convention of overriding subprograms for types derived from the interfaced type (they must be C++), the user is forced to insert a convention C++ pragma for each subprogram to make the program legal. This is unfriendly, error-prone, and clutters up the source code. 2. If the convention pragmas on the parent subprograms are hidden in the private part of the interfacing package, the user nevertheless needs to know about them to make his program legal; this breaks the privacy rules. The ARG therefore proposes new rules, which are reasonably upward-compatible and much more friendly: 1. All inherited and overridden subprograms inherit the convention of their parent subprogram. (a language change) 2. New operations of type extensions have the convention of the type unless a new convention is defined for the operation, if this is permitted by an implementation. (a language change) 3. Derived types have as default the convention of the parent type (which is the current rule of the language) 4. The convention of the partial view of private types and private extension is the convention of the full type. (which is the current rule). Erhard said that the ARG would produce an AI on this subject (the one above) by next meeting. Technical Corrigendum Timeframe One of the technical editors, Bob Duff, is losing financial support. Otherwise, a first draft could be done by July 1998, i.e., an initial draft to look at. A target date for completing the Corrigendum is circa 2000. The corrigendum will follow the C language approach -- issues and responses. The ARG's technical corrigendum will use mainly AIs without discussion, thus it will be mostly editing the AIs. A formal printing of the AIs is a product of the ARG. We must make sure that resources are well used. The ARG's business is to be preparing a Technical Corrigenda. WG9 is required to have a formal defect reporting process and the product of that process is the Technical Corrigenda. However, the priority of using resources should be in correcting the current AIs. It was noted that SC22 insists on periodically processing proposed corrections and clarifications to standards. WG9 cannot simply maintain them on a web page without forwarding them for approval. ---------------------------------------------------------------------------- Report of Annex H Rapporteur Group: Brian Wichmann, Chair Supplementary Paper The chair of the Annex H RG has provided a supplementary paper, High Integrity Ada, which can be found at: {http://www.open-std.org/jtc1/sc22/wg9/HRG-High-Integrity-Ada.html}, {as a PostScript file (57K bytes)}, and {as a text file (33K bytes)}. Three documents were discussed at this time: the New Work Item, the acceptance criteria, and the aforementioned paper. Brian then led a discussion about why the guidelines are needed. The Supplier and Regulator need to sign-off the component that is being developed/delivered. Many suppliers provide their products to a prime contractor and suppliers may be from different countries. Many suppliers are ignorant of Ada and some regulators are not knowledgeable of Ada. Many people do not think that the language for development matters much, but the fact is that the "devil is in the details" -- that is, the language does matter. Brian concluded that the HRG want an ISO document, which can be referenced, so that people can use it for sign-off purposes. This document could be either a type 3 Technical Report or a standard. Much discussion ensued. The following resolution passed 6-0-1. RESOLUTION: WG9 is prepared to accept responsibility for a project resulting from the produced New Work Item. An amendment to the following resolution to remove Wichmann's paper passed 3-1-3. The following resolution passed 6-0-1. RESOLUTION: WG9 recommends approval of the proposed New Work Item [NWI proforma (modified to not reference the Wichmann paper), expressions of support of NBs]. The following resolution, entered by the US, to offer guidance to the HRG from WG9, passed 6-0-1. RESOLUTION: WG9 directs the HRG to present the resolution of this Work Item in a positive fashion which includes some abstraction of the regulatory rules; the resolution shall demonstrate: 1. how Ada supports these abstractions 2. how other languages support these abstractions 3. usage paradigms for resolutions of these abstractions with a subset of Ada WG9 saw this as an opportunity to show Ada's strengths to solve problems, particularly in the safety critical community. ---------------------------------------------------------------------------- Report of ASIS Rapporteur Group: Currie Colket, Chair 22.15291, WD 15291, Ada Semantic Interface Specification (ASIS), Project Editors - Steve Blake and Clyde Roby (US) As planned at the last meeting, the ASIS Working Draft was balloted by national delegations and approved. In accordance with the plan approved at the WG9 meeting of December 1996, the ASIS Project Editors prepared a revised Working Draft in accordance with the comments received during the balloting and prepared a Comment Disposition Report for consideration at this meeting. Approval of the Comment Disposition Report authorizes the Convener to forward the revised Working Draft to SC22 for CD registration. A number of comments came in; ASISRG divided these into Editorial Comments and Technical Comments. A Comments Summary and all Editorial Comments were distributed with their resolutions and appropriate rationale. These are available electronically at: {http://www.acm.org/sigada/WG/asiswg/Comments-Summary.html}. An Issues Summary and all technical Issues were distributed with their resolutions and appropriate rationale. These are available electronically at: {http://www.acm.org/sigada/WG/asiswg/Issues-Summary.html}. Note that issues submitted as a result of WG9's review begin with Issue #023. The WG9 balloting process resulted in 90 Editorial Comments and 57 Technical Comments (Issues). Those comments approved by ASISRG were incorporated into ASIS version 2.0.M, distributed to WG9 on 1 May 1997 (except for three comments, now incorporated into ASIS version 2.0.N and discussed below). Editorial Comment #076: Provide an Index -- An index is now provided with Ada syntactic categories denoted in lower case and ASIS interfaces denoted with the first letter of underscored terms in upper case. Technical Comment #041: Example B.3 Does Not Compile -- Example B.3 could not be made executable for ASIS version 2.0.N, so it was removed. Dr. Sergey Rybin did implement ASIS version 2.0.M in ASIS-for-GNAT to test the execution of Examples B.1 and B.2; these execute correctly. Technical Comment #047: Paragraph and Line Numbers -- The line numbers have been removed to conform with ISO standards. Paragraph numbers were not added as ISO does not use paragraph numbers. These would have been difficult to automatically generate as much of the ASIS paragraphing is provided in the form of compilable Ada comments. Since the delivery of ASIS version 2.0.M to WG9, the status of Technical Comment #064 was changed: Technical Comment #064: Ada Wide_Character and Wide_String -- As a result of discussions at the March meeting in Phoenix, we added about 42 duplicative interfaces; of these, nine created a problem. Their names were changed from XXX to Wide_XXX as a result of a compromise solution in the last two weeks. A possible better solution would be to provide ONLY Wide_String; however, this issue will continue to be discussed over the next few weeks. ASIS version 2.0.N was distributed in hardcopy and in electronic form (as a Word 6.0 document and as a PostScript file). There is an index of ASIS terms as well as Ada syntactic terms in this latest version of ASIS. Before the vote on the following resolution, Convener stated that if the following resolution is approved, he will forward ASIS on to SC22 for Registration as an ISO Committee Draft (CD). The following resolution passed 8-0-0. RESOLUTION: The disposition of comments on the ASIS Working Draft ballot is approved by WG9 and the Project Editor of project 15291 is authorized to forward Version 2.0.N of the draft to the SC22 secretariat for CD registration. The following resolution was passed 8-0-0. RESOLUTION: WG9 authorizes Convener, in his judgment, to combine CD registration and CD ballot. The following resolution was then voted on and passed 7-0-1. RESOLUTION: WG9 authorizes Convener, in his judgment, to combine CD registration and CD ballot and Final CD ballot. ASIS version 2.0.N is now under configuration control. If format changes are needed by the ISO secretariat, ASISRG will do that before forwarding to SC22 for registration as an ISO CD. Otherwise, no further changes can be made to ASIS at this time. It was noted that the first ASIS 95 commercial tool, ObjectMaker by Mark V Systems, was demonstrated at the Software Technology Conference (STC'97). A syntactic parser and semantic analyzer for Ada 87 was replaced with ASIS 95 calls. Only five days were needed to replace the part that had previously taken 6 1/2 staff-years of effort to create. There are a number of people who have worked very hard to get ASIS to where it is today. We are indebted to the ASIS Working Group and ASIS Rapporteur Group members who spent many hours evolving an ASIS for Ada 83 to an ASIS for Ada 95. We are indebted to the work of the National reviewers who provided excellent comments which will result in a significantly improved ASIS specification for the Ada community. We are indebted to the many who helped resolve these issues. These creators, reviewers, and resolvers included: Cheryl Barbasch, Gary Barnes, John Barnes, Bill Beckwith, Roy Bell, Jim Bladen, Steve Blake, Alex Blakemore, David Brookman, Gary Bundy, Dave Clark, Dan Cooper, John Dawes, Robert Dewar, Bill Eastman, Bob Ekman, Dan Ehrenfried, Dan Eilers, Magnus Ericson, Arthur Evans, Dan Fisher, Herm Fischer, Vasiliy Fofanov, Wesley Hair, Hal Hart, Peter Hermann, Chuck Hobin, Bob Hokanson, Rick Hudson, Kiyoshi Ishihata, Jesper Joergensen, Bjorn Kallberg, Magnus Kempe, Allan Kopp, Alain Le Guennec, Robert Leif, Pascal Leroy, Jim Longers, Ole Oest, Stefan Landherr, Bob Mathis, Jim Moore, Peter Obermayer, Bertrand Petitprez, Michael Pickett, Erhard Ploedereder, Ron Price, Gil Prine, Dan Rittersdorf, Clyde Roby, Sergey Rybin, Tom Shields, Steen Silberg, John Solomond, David Spenhoff, Doug Smith, Tom Strelich, Alfred Strohmeier, Joyce Tokar, Bill Thomas, Kevin Tucker, Luba Vladavsky, Mickey White, Steve Ziegler, and many others. A very, very special thanks to those who served in key positions in making ASIS happen. These folks are: Currie Colket (ASISWG Chair/ASISRG Chair), Steve Blake (ASISWG Vice Chair, ASISRG Co-Editor), Clyde Roby (ASISWG Recorder, ASISRG Co-Editor), Dan Cooper (ASISWG Vice-Recorder), Dr. Bill Thomas (ASISWG Vice Chair for Publicity/Meetings), Gary Barnes (ASISWG Archivist), Cheryl Barbasch (Active Member), Dr. Robert Dewar (Active member), Bob Hokanson (Active Member), Jesper Joergensen (Active Member), Dan Rittersdorf (Active Member), Dr. Sergey Rybin (Active Member), Steen Silberg (Active Member), Professor Alfred Strohmeier (Active Member), and Dr. Joyce Tokar (Active Member). Several monumental efforts should be recognized: Sergey Rybin rapidly brought ASIS-for-GNAT to ASIS version 2.0.M, making possible the testing of the examples by Bill Thomas; and Clyde Roby and Steve Blake did a fantastic job as technical editors. A very special thanks goes to Clyde Roby who is truly a wizard at generating a large technical document and making the World Wide Web effective for the dissemination of ASIS information via the ASIS Home Page. His work in providing ASIS and the Resolution of Editorial and Technical Comments on the ASIS Home Page was vital to the success of ASIS. And yes, a special thanks goes to Dan Ehrenfried whose idea for the LRM interfaces mushroomed into ASIS. Currie Colket remarked that it was a distinct pleasure to work with a highly professional and cooperative team dedicated to producing a powerful interface to the Ada compilation environment. ---------------------------------------------------------------------------- Report of Numerics Rapporteur Group: Convener 22.10.02, IS 11430:1994, Ada Numeric Functions, Project Editor - Ken Dritz (US) 22.10.03, IS 11729:1994, Ada Primitive Functions, Project Editor - Ken Dritz (US) 22.10.04, DIS 13813, Ada Complex Functions, Project Editors - Don Sando and Ken Dritz (US) 22.10.05, DIS 13814, Ada Complex Elementary Functions, Project Editors - Jon Squire and Ken Dritz (US) We can support the above two documents through DIS resolution now since we have project editors in place. The following resolution was passed 8-0-0. RESOLUTION: Having completed their chartered mission, the Numerics Rapporteur Group is discharged with the grateful appreciation of ISO/IEC JTC1/SC22/WG9. The NRG has made important contributions to Ada technology through: (1) the drafting of supplementary arithmetic standards 11430 and 11729; (2) the drafting of the Numerics Annex of the Ada 95 standard; and (3) the drafting of two DIS documents for Complex Arithmetic. The NRG's achievements have been widely recognized including recognition as recipients of an Ada Distinguished Service Award, presented by SIGAda. The indicated individuals will continue to be listed as Project Editors of the existing standards and the two new drafts. As many of you know, funding problems endanger the active support of these editors. So further changes may become necessary. ---------------------------------------------------------------------------- Liaisons and Other Related Work WG4 (Cobol): Ben Brosgol No report. WG11 (Language Independent Standards): (No active liaison) We may have a candidate. WG14 ( C ): (No active liaison) This Working Group has expressed a desire to work closely with other language WGs to specify inter-language calling conventions. We should send them a copy of what we're doing with respect to interfacing with the C language (in ARG). WG15 (POSIX): Ted Baker This is on a fast-track ballot at JTC1. X-Windows bindings have stalled. Sockets bindings are still open; much POSIX work is falling off due to lack of participation. An issue was raised about whether sockets should be implemented as tagged types (Ada95) or not (Ada83). POSIX real-time interest has fallen off; smaller companies are doing the work but can't put resources on standardization efforts. WG16 (LISP): (No active liaison) No report. WG21 (C++): (No active liaison) No report. SC21/WG3 (IRDS): Currie Colket It was noted that the IRDS Ada binding is the first Ada 95 ISO standard binding. The reference to that document is: Amendment 2:1996 to ISO/IEC 10728:1993 Ada language binding Number of pages: 20 The base document is: ISO/IEC 10728:1993 Information technology -- Information Resource Dictionary System (IRDS) Services Interface Number of pages: 108 The following resolution was passed: RESOLUTION: ISO/IEC JTC1/SC22/WG9 expresses its grateful appreciation to Currie Colket for his service as liaison to SC21/WG3 (IRDS). SC22 JSG (Java Study Group): Bob Mathis From Bob Mathis, Convener, SC22 Java Study Group (JSG) -- Sun decided to apply for PAS (Publicly Available Specification) submitter status and use that approach for initial standardization of Java. The JTC1 ballot on this application closes July 14 so the results at not yet known. There has been some discussion on this topic on the JSG mailing list. There have been more formal public comments associated with the US voting process. ECMA TC-39 has completed its initial work in developing a standard based on JavaScript and JScript. Bob expects it to be approved by the ECMA General Assembly at the end of June and submitted for ISO Fast Track processing very soon after that. Anyone interested in reviewing that standard should contact Bob directly. The JSG will hold its next meeting, June 30 - July 1, 1997, at BSI in London, UK. More information can be obtained: about the Java Study Group from {http://www.open-std.org/jtc1/sc22/JSG}, about the US consideration of Sun's application from {http://www.jtc1tag.org}, and about the ECMA TC-39 from {http://www.ecma.ch}. Participation in the work of JSG is welcomed; information about the mailing list is on the Web page. Other questions can be sent to Bob Mathis directly: {bob@pithecanthropus.com}. IEEE CS SESC: Jim Moore IEEE Std 990 (PDL/Ada) will be administratively withdrawn this year because there is no interest in updating it to the level of Ada 95 and object-oriented technology. ARA: Joyce Tokar ARA met at Tri-Ada'96 (all members were present except for Rational). There have been no meetings since then. Oliver Cole says to "lay low" until interest in Ada95 increases. The AdaIC is now administrator of ARA's stuff. ---------------------------------------------------------------------------- Unfinished Business The following resolution passed.
