I'm pretty sure that the support is intended to allow a server address
space to access the FBA device, not to allow allocation to an
unprivileged job.
Absolutely! An authorized server address space will be necessary to
allow non-privileged programs to do FBA I/O. The requirements of the
IOSFBA service are:
*01* ENVIRONMENT:
* Dispatchable unit mode: Task mode.
* Minimum authorization: Supervisor state, PSW Key 0.
* AMODE: 31- or 64-bit.
* ASC mode: Primary.
* Cross Memory Mode: PASN=HASN=SASN.
* Interrupt status: Enabled for I/O and external interrupts.
* Locks: No locks held.
