Nobody who knew anything about language design ever expected that Ada (or any language) could meet such an objective. The objective was to minimize portability problems - much more likely to be achieved. I'm afraid I don't know about Data General building an Ada compiler and I don't know why they would be using a VAX instead of a Data General platform. But I do know that there are lots of "100% compliant" Ada compilers available if, by compliant, you mean a compiler that has run the Ada validation suite and been given a certificate stating that it has met the standard. You may be setting up a strawman here and then knocking him down. I don't think anybody had any illusions about Ada being perfect in every way. Certainly Ada had its problems in the early days because of inefficient implementations, lack of understanding and acceptance by its intended market and so on. But things have improved very considerably since the first standard was issued and it is successfully used in a wide variety of applications where it does, in fact, reduce errors, improve productivity and enhance portability. If there is some other language out there which is 100% platform transparent and has no flaws at all, I'd sure like to hear about it. But in the mean time, I think Ada does a better job than any other language I know of for avionics and other complex systems with high reliability requirements. If you have a better alternative, please mention what it is.
