If existing software is to be re-written from current
languages to Ada, aspiring software-engineers like myself will
have to know how to read stuff and nonsense such as CMS-2,
Jovial, etc.
How can I do this? Are there public domain implementations of
these languages? What about books or CBT? Who manufactures
these translators?
I am receiving the Ada-Jovial Newsletter, (Thank-you very much
to the folks there!) but I need more!

Nowhere in the DoD mandate or implementation policy is it required to
re-code working applications in Ada. Generally the standard industry
rule of thumb is that if old code needs to be changed at more than about
the 30% level, it should be tossed and re-done from the design. It
shouldn't be necessary to go back into old code just to move a system
to Ada.

I doubt that PD implementations are out there. These languages have been
(unlike Ada, which has a growing non-defense following) _exclusively_
used in the DoD-type community, and sometimes (like CMS-2) only within
one service.

Your curiosity is admirable but unnecessary. Better to spend your
energy getting good at current languages, IMHO.
Cheers -

Don,
Call Marion Rucker at (513) 255-4472, she has Jovial CBT and
programming manuals and other materials for distribution. She
works in the office that distributes the "Ada Jovial Newsletter",
as do I.
Thanks,
Eric
