The DoD standards define both the Ada language and the environment
under which it runs.  It *is* possible to have the language without
the full environment.

Right, but there are *real* disadvantages to languages like COBOL
that can very definitely make retraining and converting worthwhile,
especially when migrating to new hardware.  Us computer science
weenies are in a position to evaluate the relative strengths and
weaknesses of various programming environments; and we try to promote
those that we feel have the most to offer in a particular situation.

I don't use Ada, but I know enough about it to know that I probably
wouldn't like programming in it.  And as a computer scientist I
question whether it will ever be a viable real-time programming
language.  It seems like its goals are self-contradictory: to provide
every imaginable feature with high performance real-time execution.
At least they aren't asking for quick compilation. :-)
