At the last DECUS convention, VAX/ADA was announced and should be
available shortly (I assume). From the discussions, it appears to
meet this year's (or 84?) validation requirements. I don't recall if
it was validated or is in the process. It will be supported by the
new VMS version 4.0 language sensitive editor and (screen !!)
debugger.

This definately seems to be your personal opinion of the difference
between C and Pascal. Except for Berkeley Pascal, I have found Pascal
speed virtually identical to C. Telesoft Ada is written in Telesoft
Ada, and the reason it is slow is that Telesoft Ada uses pseudo-code.
This allows for portability and is why Telesoft Ada is available on
more machines than any other Ada. It also means you can have a
validated Ada on an IBM-pc (not a subset).
