Wichmann (National Physical Laboratory) Mr. Mike Woodger (Alsys) COMMENTS ON DRAFT VALIDATION POLICY TO BE REVIEWED In February, 1986, the Ada Joint Program Office (AJPO) made available for public comment the draft version of the Ada Validation Policies and Procedures document. As of April 4, the closing date for receipt of comments on the draft, hundreds of comments had been received from individuals, corporations and industry associations. The AJPO is in the process of distributing those comments to the Validation Review Team. The review team will include representatives from the AJPO, Ada Validation Organization, Ada Validation Facilities and representatives of DoD components. The review and revision is expected to take approximately 6-8 weeks. The Validation Review Team will address each of the comments received and as a result, submit their recommendations to the AJPO director for approval. Once approved, information on how to obtain the revised Ada Validation Policy will be announced in the Ada Information Clearinghouse Newsletter. MODIFICATIONS TO THE CURRENT Ada COMPILER VALIDATION PROCEDURES As a result of the May 5-6, 1986 Ada Validation Facility (AVF) Managers' meeting, the Director of the AJPO, Virginia Castor, announced the following changes to the current Ada compiler validation procedures: 1. There will now be one ACVC version per year for use in conducting formal validations, and that version will have a 12 month life. This change will take effect with ACVC version 1.8 which will become official on June 1, 1986 for conducting validations until May 31, 1987. A succeeding version of the ACVC (1.9) will be released for public inspection on December 1, 1986 and will become the official version on June 1, 1987. 2. In order to expedite the process by which Validation Certificates are awarded, new procedures will be implemented within the AVFs. AVF managers will prepare a draft Validation Summary Report (VSR) from their analysis of the vendor supplied pre-validation materials. This draft VSR will be forwarded to the Ada Validation Organization (AVO) before on-site testing and will be reviewed concurrently within the AVO and AJPO. If the draft VSR is approved by the AVO and the AJPO, the AVF manager will be notified to proceed with on-site testing, and a certificate will be prepared. If the on-site results are identical with pre- validation information supplied by the vendor, the AVF manager will immediately notify the AVO and AJPO to confirm successful on- site testing. The Validation Certificate will then be signed by the Director of the AJPO before receipt of the final VSR. This procedure will only be used, however, when there are no problems with the draft VSR or with on-site testing. In order for vendors to benefit from these new procedures, they must cooperate fully with the AVF manager's requirements for pre-validation materials and must meet the respective deadlines for submission of these materials. NINETEEN Ada COMPILERS VALIDATED Since the release of our JAN-FEB Newsletter, nineteen Ada compilers have been awarded validation certificates by the Ada Joint Program Office. All of the nineteen compilers were tested under ACVC Version 1.6. Of the nineteen, three are revalidations. A vendor's Ada Compiler is validated for a period of 12 months beginning on the date of validation. There are currently 29 validated Ada compilers as of April 2, 1986, listed alphabetically by vendor. Several new compilers are completing validation under ACVC Version 1.7. For a complete listing of all validated Ada compilers, call the Ada Information Clearinghouse at (703) 685-1477.

FIRST ANNUAL ASEET SYMPOSIUM The Ada Software Engineering Education and Training (ASEET) Team was established by the AJPO to formulate an approach to meeting DoD Ada education and training needs. The First Annual ASEET Symposium will be held June 10-12 at the Orlando Marriott in Orlando, Florida. The purpose of the ASEET Symposium is to provide a forum for universities and Government training agencies to review first hand a comprehensive sample of the Ada software engineering education and training materials now available. This will be accomplished through a series of vendor presentations and open exhibits. Vendor presentations will be scheduled for Wednesday, June 11 and should last approximately ten minutes each. Vendor exhibits will be free, and the exhibition hall will be open on Tuesday and Wednesday from 1:00 p.m. to 8:00 p.m. and on Thursday from 10:00 a.m. to 5:00 p.m. Other activities include a complimentary Ada tutorial on Tuesday, and on Thursday, a panel discussion regarding lessons learned in establishing an Ada software engineering curriculum to train staff personnel in Ada. For reservations, contact the Orlando Marriott at (315) 351-2420. For registration or for further information regarding the Symposium, contact Cathy McDonald at (703) 824-5531. AFCEA ACTIVITIES The Armed Forces Communications and Electronics Association (AFCEA) is currently performing a study for the Department of Defense to define education and training needs for the support and advancement of the Ada programming language. The effort will focus on three areas: requirements for Ada education and training; information on ongoing efforts by Government, academia, and industry; and recommendations and alternatives for future efforts in Ada education. To further aid the progression of the study, a workshop was held at the AFCEA conference, at the Washington, DC Convention Center, during the last week of May, 1986. The AFCEA Conference included a workshop, at which Virginia Castor, Frank Druding, Herb William, Bill Terwillegar, and Jim Fisher gave various presentations regarding the AFCEA Study and specific education and training concerns. Education and training methods and the training requirements needed to meet demands for developing and supporting military systems were among the key issues discussed. Other topics addressed included education and training requirements and approaches for defense/Government, as well as industry in the U.S. and the overall NATO arena. Comments and suggestions collected at the workshop will be added to the information and ideas gathered from the AFCEA study team, and should prove to be valuable as the study progresses to completion later in 1986. The schedule for the AFCEA Study is as follows: April - July Data gathering and analysis May Interviews completed August Complete analysis September/October Complete conclusions and recommendations November/December Complete final report DoD Proposes Multinational Collaborative APSE Effort On February 17, 1986, during a special meeting of the NATO Conference of National Armaments Directors (NADs), a Statement of Intent (SOI) to explore cooperative developments to enhance Ada project support environments was signed by the NADs from Canada, France, Germany, Italy, Spain, United Kingdom and United States. At this meeting, the US NAD offered to provide to the attendees a White Paper on Ada which would describe what the United States would propose to do with its Allies in furtherance of the signed SOI. On March 25-26, 1986 a meeting was held of the Special Working Group (SWG) on APSEs to establish the feasibility of a collaborative effort. At the CNADS meeting held on April 15-16, Belgium, Netherlands and Norway were added to the SOI. The SWG met a second time on April 30 - May 2 to draft the Terms of Reference and accompanying Memorandum of Understanding to effect the SOI. In the White Paper which resulted from the initial NADs meeting, it was proposed by the United States that CAIS Version 1 be used as a basis for cooperative APSE work under the provisions of the Nunn amendment (Public law 99 - 145, Nov. 8, 1985). The provisions of the Nunn amendment were developed to promote cooperation between NATO nations in research and development on defense equipment and munitions, production, and co-production by United States contractors of conventional defense equipment designed and developed by other member nations of NATO. The main objective of the proposed effort is to achieve economies in the use of Alliance resources through cooperative efforts to enhance APSEs. These efforts would include the development of a set of software tools of which an APSE would be comprised, and the implementation of these tools upon a common set of interfaces upon two distinct computer architectures, as well as the development of an APSE evaluation technology consistent with this developed set of tools. The SWG will endeavor to improve present technologies and develop new techniques that will further NATO's effectiveness in the development and evaluation of APSEs. The SWG's effort could include the use of practical laboratory experiments, field trials, simulation facilities, symposia or seminars, workshops or other methods of scientific investigation. This effort in APSEs is focused on achieving a near term product which will be of benefit to all of the participating nations. The framework exists for developing a multinational supported APSE capability. A resulting near term multinational success in a collaborative APSE project will demonstrate this resolve and will also provide the foundation for future collaborative efforts. The purpose of the next SWG meetings, to be held June 9-13, will be to finalize the terms of reference for the Memorandum of Understanding between participating nations, and to clarify the roles that participating nations will play in the proposed effort. The Common APSE Interface Set (CAIS) Review Process As stated in the last newsletter, the comments from the proposed MIL-STD-CAIS document, submitted by reviewers from Government, academia and industry are currently being reviewed by a volunteer group (the CAIS Working Group-CAISWG) consisting of members from the KAPSE Interface Teams (KIT and KITIA). The results of this review will be submitted to the CAIS Standardization Working Group. The CAIS Standardization Working Group is set up under the authority of the Defense Standardization Program in accordance with DoD 4120.3-M procedures. This is the formal body that will deliberate the technical recommendations and reconcile essential comments. The CAIS Standardization Working Group will make the final recommendation to the Preparing Activity (PA) regarding standardization. The review process for the proposed MIL-STD-CAIS is a lengthy one. The draft CAIS document was mailed to approximately 450 individuals for informal review. During the official standardization process, this document was mailed out to DoD Components and industry associations for their formal review. About 600 formal and informal comments have been collected and logged for coordination and tracking to ensure that no comments are lost or are incompletely handled. The comments are distributed to those members of the CAISWG who have assigned responsibility for the sections to which the comment is directed. The responsible person formulates a proposed response, which is then circulated to other CAISWG members for review. If CAISWG agrees with the proposed response, it is returned for inclusion in the comment log. The results from the comments resolution stage will be several proposed corrections and enhancements to the proposed MIL-STD-CAIS, which the CAISWG will draft after the comment-review process has been completed. The results of this process will be submitted to the CAIS Standardization Working Group. Currently, the CAISWG is still generating answers to the comments. CAISWG has addressed about 320 of the 349 official comments received; the remainder are non-technical and will be addressed directly by the CAIS Standardization Working Group, or will require clarification by the submitter(s) before they can be answered. The informal comments are currently in the process of being distributed to the CAISWG. The CAIS Standardization Working Group will convene approximately 30-60 days after all the comments have been addressed by the CAISWG. Ada USAGE SURVEY In order for the entire Ada community to benefit from individual and organizational experiences acquired in the development and use of the Ada language, the AJPO sponsored an Ada usage survey. As more information is collected and verified, it will be made available through the Ada Information Clearinghouse. Thus, far, information on the following Ada projects has been collected: Program NamLines of Code Ada-AIMS 400,000 Ada Compiler System (ACS) 400,000 Ada Designed/x.25/VLSI/VHSIC Chip unspecified AdaEDIT 8,800 Ada Language System 250,000 Ada SAM Missile Simulation unspecified Ada Test Tools 2,000 Advanced Field Artillery Tactical Data Systems (AFATDS) 41,698 Air Force Support to MEECN 11,800 Automated Test Procedure Generator for Ada unspecified Concurrency Control Method for Database Indices (MU) 5,000 Design Evaluation Tool (DET) 100,000 E-4B Message Processor System 20,000 Flexible Ada Simulation Tool (FAST) 20,000 Flir Mission Payload Subsystem (FMPS) 11,000 GRAMACT 10,000 Intermediate Forward Test Equipment (IFTE) 400,000 Maneuver Control System (MCS) 34,000 Mobile Information Management System (MIMS) unspecified MSOCC Ada Study 3,000 NOSC Tools 3,000-5,000 Regency NET 75,000 RELATE/3000, Project ALERT 250,000 Relational Database System 1,000 Single Channel Objective Tactical Terminal (SCOTT) 26,600 817 Fuze Tester 25,000 Ada PRODUCTS LIST BEING COMPILED Since the Ada Information Clearinghouse has received many requests for product information, we are considering publishing an Ada products catalog, with the aim of making the Ada world aware of the products available and how more information can be obtained about them. The products catalog will be arranged by product categories (e.g., compilers, PDLs, utilities and programming support, consulting services, etc.), and will not include educational products, since a listing of those can alreadly be obtained in the Catalog of Resources for Education in Ada and Software Engineering (CREASE). If you are interested in being included in the list being compiled, please contact the AdaIC to request the proper forms for entry in our database. ACCESS TO THE Ada-INFORMATION DIRECTORY LIMITED Access to the Ada20 Information directories is now limited to authorized Defense Data Network (DDN) users only. In the near future, a dial-up bulletin board service for non-DDN users will be implemented which will allow access to files in Ada- Information and other general information directories on Ada20. Further information on public access to Ada-Information will be provided via the Ada Information Clearinghouse Newsletter and other media. Authorized DDN users can obtain instructions on accessing general information files by reading the file <Ada-Info>DDN-Access.Hlp. This file may be accessed via "type" by Ada20 users, or via anonymous FTP by users on other hosts. Ada INTEGRATED ENVIRONMENT (AIE) The AIE is an Ada Compilation System (ACS) being developed by Intermetrics, Inc., Cambridge, MA for the Air Force. The AIE system is intended for embedded computer systems development and is designed to be rehostable and retargetable. It is hosted on the IBM 4341 running the Amdahl UTS operating system. The ACS contains facilities for compiling Ada programs in accordance with ANSI/MIL-STD-1815A. The Ada language requires additional facilities for the transformation of Ada programs into executable entities. Therefore, the AIE contains facilities for link/loading and program libraries. In addition to the AIE software, the AIE contract also requires documentation, training, and one year of maintenance. The compiler has been bootstrapped (or self-compiled), currently takes less than 5 megabytes of memory and compiles at the speed of 900 lines per IBM 3083-cpu minute or 225 lines per IBM 4341- cpu minute. Intermetrics testing thus far, excluding tasking and generics, indicates approximately 5 lines of assembly code is generated from 1 line of Ada code in the average case. Formal validation is scheduled for August 1986. Ada ? ? ? Questions & Answers ? ? ? The following are a list of questions that are commonly asked to the AJPO and Ada IC. ? ? ? Dear AJPO: When was the Ada Programming Language first standardized? Answer: The Reference Manual for the Ada Programming Language first appeared as a proposed standard in July, 1980. The Ada language was approved as a Military Standard on December 10, 1980 (December 10th being Ada Lovelace's birthday) in the form of MIL- STD-1815. As part of the American National Standards Institute (ANSI) standardization process, the language was revised, finally resulting in the ANSI/MIL-STD-1815A version we know today. In accordance with ANSI procedures, this ANSI/MIL-STD-1815A version was approved on January 22, 1983, and will remain frozen until 1988. In addition, this same version of the Ada language was cited as a Federal Information Processing Standard (FIPS-119) in October, 1985, and in 1986 we are expecting the standardization of Ada by the International Standards Organization (ISO). ? ? ? Dear AJPO: What is the definition of a production quality compiler? Answer: There is no standard definition of a production quality compiler, although there is common consensus on which aspects of a compiler are important for production use. These include compilation speed, portability, quality of error messages, memory space utilization/execution speed of object code, documentation, and difficulty of retargeting. Of course, any one user may want or need different levels of quality in different performance aspects to accomplish his/her production effort. Thus, for a production quality compiler, quality is very much application oriented. To help users evaluate different Ada compilers on the market today, the AJPO has sponsored the development of a prototype Ada compiler evaluation test suite distributed by the Language Control Facility at Wright-Patterson AFB, OH (WPAFB). The AJPO is also currently sponsoring the development of a more comprehensive Ada Compiler Evaluation capability through the Air Force Wright Aeronautical Laboratory (AFWAL) at WPAFB. ? ? ? Dear AJPO: What military and non-military systems are currently using Ada? Answer: The AJPO has recently started to develop a comprehensive database of Ada usage information on defense systems. We have solicited written input in standard format from the Ada military and industrial community through Ada Letters (a publication of the Association for Computing Machinery), our own AdaIC Newsletter, and at user conferences such as those sponsored by SIGAda. Once the database is complete, we will be able to provide fully substantiated usage information to the public, but until then we are not distributing lists of U.S. DoD systems using Ada. A partial list of the information received so far on Ada usage is printed after the last question and answer in this Ada-Q&A section. ? ? ? Dear AJPO: Where is the Ada market? Answer: Within the DoD, Ada has been in the process of being implemented for mission critical systems since June, 1984. Over the years, there has been a real growth in Ada usage on DoD systems, particularly in C3I applications. Examples of major systems include the World Wide Military Command and Control System (WWMCCS) Information System (WIS), MILSTAR and Army Field Artillery Tactical Data System (AFATDS). The use of Ada on non- mission critical systems (information systems or mission support) such as pay and accounting information systems is also being pursued by the services. The Ada market outside DoD has been growing steadily in several directions at once. Commercial applications include oil seismic analysis, artificial intelligence, commercial aircraft, banking systems, robotics, database management systems, communications, health, computer-aided instruction, software components and space. In the education area, our next Catalog of Resources for Education in Ada and Software Engineering (CREASE) will list over 80 different Ada textbooks and 165 different courses now available on Ada. In addition, there are now 26 different colleges offering courses in Ada. With the recent Ada technology advances on self-contained personal computers/workstations, we expect the academic involvement in Ada as a standard, consistent and powerful language to teach computer science and software engineering to mushroom. In the international arena, several countries have declared Ada standardization policies for military systems and have sponsored R&D activities in Ada. Prominent examples include: United Kingdom, Germany, Canada, and Sweden. In addition, Ada is now effective as the single HOL for NATO, and we expect ISO standardization in 1986. All of this has generated a world wide Ada market in military and commercial systems. The Commission of the European Communities is investing heavily in Ada technology, and Ada programming support environments have been sold to the Japanese.
