Continuing the debate, I am asked to repost this (but I was warned to proof read it first, this time!). ---------- >> As per Richard Fairley (Software Engineering Concepts, 1985, Ch. 7, >> Page 229), Ada is part of "the technology of software engineering". ^^^^ correct, ada is only an instantiation of a particular and very miniscule facet of s/w engineering (the programming part). >> . . . The question is whether Ada is >> to become an *obsolescent* software engineering technology, just >> as COBOL did before it. it already has. it is 60's and 70's technology. don't look now but the '90 are just around the corner.

(Finally - a post that actually *IS* from me!) From the self-same article extolled by one of the other post-ers on this bboard, "Ada: Past, Present, Future" from CACM, October 1984, an interview with Jean Ichbiah: "I see the global architecture of Ada as a cathedral, with all the architectural lines interwoven in a harmonious manner. I would not do it differently if I had to do it over again." Also from the same article, in response to the question: "Would you expect that to be a relatively minor revision?", Ichbiah responds, "It is probably too early to say, but I tend to think it would be a very minor revision." And, just as a reminder, Jean Ichbiah is one of the Ada 9X Distinguished Reviewers. One should always know one's history and the key players before making assertions about what could/should/might get accomplished ... Judy Bamberger

At that time, the ISO standard was only around one year old, and few if any validated compilers existed. Hence, there had not yet been an opportunity to put Ada through its paces and find out where the problems were. Nor had there been the benefit of the tremendous amount of research that has been done on object-oriented concepts since that time. What this quote tells us is that he was (quite justifiably) pleased with what he had done, in view of the information which was available at the time. Considerably more information is available today. > Also from the same article, in response to the question: > "Would you expect that to be a relatively minor revision?", > Ichbiah responds, > > "It is probably too early to say, but I tend to think > it would be a very minor revision." Yes, it was indeed too early to say. > And, just as a reminder, Jean Ichbiah is one of the Ada 9X > Distinguished Reviewers. > > One should always know one's history and the key players > before making assertions about what could/should/might > get accomplished ... This sounds like some sort of implication that Ichbiah has not changed his position in the least during the five years in which Ada has been given a much more comprehensive review, despite articles such as "Programming Atomic Actions in Ada" (Burns & Wellings, Ada Letters, Sep/Oct '89); this article in particular demonstrates that recoverable atomic actions cannot be performed in Ada due to the lack of an asynchronous exception facility. A number of other major shortfalls in the tasking area are also rather well-documented. I don't think that Jean Ichbiah would be very favorably impressed by any sort of implication that he is somehow incapable of learning from the results of his Ada 83 experience.
