Well, I've been reading the listings since V1.5 (well before Ada existed)
at client sites.  Could someone have slipped in some isolated Ada I did
not find, yes, but it would be unlikely.  The major part that is in Ada
now was created from scratch for V6.2 or so, with no predecessor in any
language.

VAX Pascal and VAX Fortran are sort of unique because they have their
own code generator.  Most VAX compilers from DEC use VCG.
