This is true.  For almost all _new_ DoD contracts (with VERY limited
exceptions), all software must be written in Ada using a DoD-approved
Ada compiler.  For the company I worked for this past summer, we had
to convert all of our Pascal source to Ada.  'Course, since Ada doesn't
support Curses internally, we had to use the good ol' PRAGMA directive
a few times.. :-)

Actually, one thought was to write everything in C, and have the Ada
program call the C code.  Unfortunately, I don't think DoD would be
too appreciative.

>From what I understand, NASA "encourages" software to be written in
Ada, but it is NOT required.  Reason: Most Ada compilers simply produce
code which is too big and/or too slow.  Example: On 3 different Unix
compilers, a "Hello, world" program produced code ranging in size of
89.9K to 107K.  (not meant as a scientific example, so no flames please! :-)

I don't know if it's THAT large, but in my experience, there is most
certainly a shortage.  In fact, is you have "Ada" listed on your resume,
you have very good odds of getting a job with a defense contractor..

This I haven't heard.  Then again, I can't think of any Ada-based computer
science programs off the top of my head either.

As an interesting note: a relative of mine went to a seminar given by one
of the members of the Ada design committee.  He opened with this:
"Ada was designed to be used for embedded systems software.  Of course,
you _can't_ use it for that, but..." :-)

Flames to /dev/null -- I actually started getting used to the language! :-)
(did anyone know that GNU Emacs has an Ada mode?)
