Perhaps your IARV64 request is wrong and not asking for what you think
it is.
SEGMENTS=xsegments
is the name (RS-type), or address in register
(2)-(12), of a required doubleword input that
specifies the size, in megabytes, of the memory
object. This must be a non-zero value. The
amount of storage requested that is not in the
guard state is charged against the MEMLIMIT for
the address space where the memory object is to be
created.
IEFUSI is in common storage, probably LPA, but could be MLPA or
dynamic LPA. AMBLIST is one way to find it, D PROG,EXIT operator
commands and also various IPCS commands (LPAMAP, FINDMOD).
One way I have tested IEFUSI effects without having IEFUSI code is to run my
REXXSTOR program in batch with different values. There is also an example
of that on my web site - REXXSTOJ.
