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.
