The subject says it all: is there any Ada compiler for MVS mainframes?
Thanks for any information

There is currently no Ada 95 compiler for MVS. Probably the
easiest path would be a GNAT port, since there is a gcc
available for MVS, but this would not be a trivial port,
and in particular specialized work would be needed to get
the tasking and tools working.
There were at least four Ada 83 compilers for IBM
mainframes of various vintages, from Telesoft,
Intermetrics, Alsys, and Systeam. I do not know if
any of these survive in supported form. Try contacting
OCSystems and Intermetrics for information (I am pretty
sure that Aonix no longer supports the old Alsys technology
and I am quite sure that Aonix (who swallowed Systeam many
mergers and acquisitions ago) does not support the Systeam
compiler any more).

There seems to be in fact two possibilities for a GNAT port to OS/390
(the new correct name today of MVS, sorry for the confusion):
1. A port to OS/390 itself.
2. A port to "OS/390 UNIX System Services" (see
http://www2.s390.ibm.com/oe/index.html). It seems to be an Unix layer
added on top of OS/390.
The second solution should hopefully be easier than the first one. Which
one would you qualify as "non trivial"?

And not sufficient for some purposes.
When someone says they want support on "MVS", I presume they want
it to run correctly at those site who choose not to run the "Open
Edition" subsystem.

Another possibility is to use our Ada 95 front end which has
a variant that generates optimized ANSI C as its intermediate
code, and uses the standard C run-time to implement exception
handling, tasking, and abort.
Let us know if you are interested.

I don't know of any widespread use, or a poular compiler. I remember
seeing books on ADA/370, which I guess is an IBM Ada compiler. When I saw
these books, there was no Ada95, and I don't think the compiler was ever
upgraded. I am sure IBM will know more.
With OpenEdition MVS (also know as Unix System Services), you can use gcc.
This suggests that GNAT could be ported. If you try this approach, I
suggest asking on the MVS-OE mailing list. They are very helpful.
