Hi, sorry I'm not able to reply to this properly.  I got this as
mail forwarded to me (I'm not on internet enough), I wasn't able
to see this original posting, only replies to it, and now my server
isn't even showing me the replies.  I can however see postings
much older than Feb 11, the date this was posted.  Sigh!

Likely support for this is in OpenVMS Alpha V7.1, which supports
Kernel Threads (see VMS documentation for more information).  DECthreads,
which DEC ada uses to implement Ada tasking on Alpha, gives the kind
of support we need for allowing DEC Ada tasks to run on multiple
processors.

We are in the process of testing DEC Ada on OpenVMS 7.1 to confirm
our general support.  We have run the subset tests which would be
likely to give us problems, and saw no problems.  We did a lot of
this subset testing while the VMS engineering group was developing
Kernel Threads.

I saw some postings from Robert Dewar who I assume answered this
to your satisfaction.  Gnat is in field test now.

For more help with either topic, you can contact me or the DEC Ada Product
Manager, Cathy Axel (axel@teamlk.dec.enet.com).
