We (Ada Core Technologies) have a lot of experience in successfully porting
Verdix Ada 83 code to GNAT -- I am talking programs in the 250,000 to one
million line range here -- for several major customers. It is something that
we can definitely provide assistance for. If you want to find more about
how we could help, send email to support@gnat.com.

P.S. I know this is a bit close to commercial advertising, but at least no
one can say that is *all* I post on CLA :-) and this seems to be informatoin
which might be of use to a number of readers.
