Ada 95 Validation Test Suite and "Passing" Criteria Upgraded
AJPO Notes: Ada users honor Donald Reifer

Ada 95 Validation Test Suite and "Passing" Criteria Upgraded
The Ada 95 Ada Compiler Validation Capability (ACVC) has been upgraded. On Mar. 31, 1996, ACVC 2.0 will be replaced by ACVC 2.0.1.

Some withdrawn tests restored
A number of tests have been withdrawn from ACVC 2.0 because of problems. ACVC 2.0.1 restores those tests for which the problems have been corrected. (Most of these tests are from the group known as Ada 9X Basic -- which validates those aspects of the language shared by both Ada 95 and Ada 83 but with some changes in language rules for Ada 95, e.g., checking static types).

The Ada Compiler Validation Procedures document has been updated (version 4.1) to reflect the new ACVC version and also to reflect a change in the "passing" criteria for Ada 95 validation certificates.

New passing criteria
For Ver. 2.0, it was sufficient to pass all the Ada 9X Basic tests. In effect, Ver. 2.0 guaranteed that a compiler would have no incompatibilities with Ada 95, but did not mandate that all Ada 95's new core language features be passed.

Responding to user need for Ada 95 features, ACVC 2.0.1's mandatory criteria for obtaining an Ada 95 certificate are passing all applicable

Ada 9X Basic tests and passing all applicable tests for either real-time or object-oriented programming in the core language. These last features are two of the highest user demand areas of Ada 95, and areas where compiler vendors have already shown the greatest support.

(With either ACVC 2.0 or ACVC 2.0.1, certificates issued for validation will expire at the same time -- Mar. 31, 1998.)

To obtain the Procedures document
Version 4.1 of the Ada Compiler Validation Procedures is expected to be available by January 1996.

Hardcopies will be available through the Ada Information Clearinghouse (800/232-4211; 703/681-2466). Electronic copies will be available through the AdaIC Internet host (

AJPO Notes...

Ada users honor Donald Reifer
At the last AJPO Program Manager's Review meeting on September 20, in Falls Church, Virginia, members of the Ada community honored outgoing AJPO Chief Donald Reifer with a plaque in recognition of his service and commitment to the Ada language. The award was given on behalf of NCTAMS LANT (Naval Computer & Telecommunications Area Master Station Atlantic); NCTS (Naval Computer Telecommunications Station, San Diego; and the Information Systems Technology Center, Pearl Harbor.

Mike Shumate, Director, Software Technology Dept, NCTAMS LANT, who presented Mr. Reifer with the plaque, commented that "Mr. Reifer's commitment to excellence has shaped the environment in which hundreds of Ada Software Engineers within DoD perform daily." Mr. Shumate also added that Mr. Reifer is a pioneer who has been a "leader and a provider who made a difference."

 A comment on the language
Dear Mr. Reifer:

Thank you for sending me a copy of the recently published report by the Institute for Defense Analyses (IDA) entitled A Survey of Computer Programming Languages Currently Used in the Department of Defense."

I am pleased to see that more than 2/3 of the Source Lines of Code in weapons systems are in no more than three languages. This reduction of a proliferation of languages is a major improvement.

As the Department's budgets continue to be decreased, it is imperative that we reduce the cost of weapon system ownership. I wish you continued success in further reducing the proliferation of languages of future weapon systems.


Anita K. Jones
Director, Defense Research and Engineering
