Restrictions

This service cannot be invoked by callers running as a disabled interrupt exit (DIE).
The caller's parameter list must be addressable in the caller's primary address space.
If the caller is running in AR ASC mode and specifies a parameter using register notation, the access register corresponding to the general register must appropriately qualify the general register.
The virtual storage areas specified by ADJAREA, ANSAREA, NSBAREA, and STGSTATS must be addressable in the caller's primary address space or from the caller's PASN access list. On a REG_NAMELIST request, the virtual storage area specified by BUFFER must be addressable in the caller's primary address space or from the caller's PASN access list.
The virtual storage areas specified by parameters other than ADJAREA, ANSAREA, NSBAREA, and STGSTATS (and BUFFER on a REG_NAMELIST request) can be addressable in the caller's primary, secondary, or home address spaces, from the PASN access list, or from the dispatchable unit access list (DU-AL).
If the caller is disabled, then the parameter list and all storage areas addressed by the parameters must reside in either nonpageable or disabled reference storage.
If you specify BUFLIST and PAGEABLE=YES, all the buffers in the list must be in the same area of storage; you cannot mix common and private storage in the list of buffers.
