Ed,
My tests indicate that DYNALLOC is in fact colliding on SYSZTIOT with the
SSI Open/Close logic. Could you elaborate a bit on how exactly your BPAM
subsystem avoids the collison?
Thanks!

That information might be proprietary. I'll have to check into this.
I'll get back to you
Judicious use of S99TIONQ?
Maybe use S99CNENQ first?

Victor,
Chapter 25 of MVS Programming Authorized Assembler Services Guide describes
(such as it is) the use of DYNALLOC as well as some suggested
restrictions. There are a few places where they recommend against the use
of DYNALLOC with several of those cases being the intersection of

Thanks again for your invaluable input. Suppose the DYNALLOC is still
restricted from being issued from within the SSI Open - it can be easily
deferred up to the first GetPut request [although at this time I wouldn't
be able to correctly inform the user had the file failed to allocate or

Careful! According to legend, that's the kind of thing that begat IEHMOVE.

First of all, I'd like to thank everybody who helped me with the subsystem
documentation and debugging, especially, Sam Knutson, Tom Schmidt and
Binyamin Dissen - your input was much appreciated.
Let me also share some of the experience [for the archive]:

Thanks for updating us on your experiences, Victor. Can you tell us what
you're doing with this SSI experiment?
Whatever it is, I'm curious if you also looked at the UNIX PFS (Physical
File System) APIs as a way of implementing your application.

Tony,

We have a subsystem that emulates BPAM for a proprietary library system
that does just that!

Tom,
I was thinking of doing dynalloc in the subtask attached by Open. Why? Any
sort of ENQ I should be aware of? I've seen products that parse the SUBSYS
dd and perform dynamic allocation.
