Hi Binyamin,

   We've jumped back to 1.9 on our sandbox system for now (to test
fallback from 1.11), so I'll have to recreate the problem when we're
back up on 1.11.

   Best as I can remember (and I don't have the output - DUH!), the
error message was in the CEEMSG or CEEDUMP DD, but I don't remember the
file status.  We added a DD statement to the JCL, and it worked fine.
It didn't even write to the DD!  From reading the Fine Manuals, it
appears that I can code DYNAMNBR on the EXEC statements - which seems a
better solution than coding individual DDs if I end up having to change
the vendor PROCs anyhow.  

   Thanks for the response, and I'll repost when I can recreate.

   Happy Holidays!

Thanks!
BobL

What are the exact details of the dynamic allocation error? It may be a
generic unit problem, for example.
