Could someone summarize for me where one can obtain Ada compilers for Vax/Unix machines? Any other information you want to throw in would be appreciated. Reply by MAIL and I will summarize to the newsgroup. Note that I have the "followup-to" header set to try to foil non-mail replies.

Sorry folks, it's been a long time since I posted my request for information on vax/unix ada implementations. Here is the long-awaited summary of responses. I don't want to argue over whatever qualitative judgements I may be promulgating, so I have more or less bowdlerized the messgaes. These messages are kind of old; my apologies if they're not up to date. Liudvikas Bukys rochester!bukys (uucp) via allegra, decvax, seismo bukys@rochester (arpa) ------------------------------------------------------------------------------- Only one I know of, Liud, is the TeleSoft ADA. The one we have running here is a subset (dirty word in DoD land), but I think they have the full language version available now. ------------------------------------------------------------------------------- At this point in time, you have 2 choices: For Sun's and Vax's running 4.2BSD (System 5 should be shortly): Definitly Validated on Sun: Telesoft Likely to Validate on Vax Soon: Telesoft, Verdix Likely to Validate on Sun Soon: Verdix Here are some stats for a Vax Ada compiler: The Verdix compiler is very fast 1000/lpm and better! The Telesoft is a bit slower and at about 300-400/lpm. The Verdix Ada compiler is written in 'C' and the Telesoft Ada compiler is written in 'Pascal' (hence the speed difference). The people have been at Verdix have been very helpful in providing info even though we are only evaluating characteristics. Contact: James A. Zimpher Verdix Corporation McLean, Virginia (703) 448-1980 ------------------------------------------------------------------------------- try Intermetrics or SofTech, all in the Boston area. they have had contracts to the Air Force and Army (respectively) for Ada compilers for the VAX. Also try Tartan Labs in Pittsburgh and the University of Karlsruhe in W. Germany. also try the Ada SIG newsletter from ACM. -------------------------------------------------------------------------------

> Definitly Validated on Sun: Telesoft > Likely to Validate on Vax Soon: Telesoft, Verdix > Likely to Validate on Sun Soon: Verdix 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. > The Verdix Ada compiler is written in 'C' > and the Telesoft Ada compiler is written in 'Pascal' (hence the speed > difference). 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).
