> RR Software in Madison, Wisconsin has had an Ada to Pascal translator

Your Freudian slip is showing, Richard  :-)

Laurent Gasseur (apologies if I misspelled) created a Pascal to Ada
translator/grammar suitable for aflex/ayacc.  I have no idea where he
keeps it, but I do have a "beta" version.  I'd rather Laurent release
it though, but I can no longer locate his e-mail address.

If you get truly desperate, wrte me and I'll provide it (I'm using it
as a partial guide in a C++ to Ada translator I'm tinkering with, but
it's a long away from any kind of release).
