#GETSTG Status Codes

By default, the #GETSTG request is unconditional. Error conditions that can occur are:

A short-on-storage condition, caused when the amount of storage in the storage pool is inadequate to accommodate the request, will result in a delay until sufficient storage becomes available (unless such a wait would cause a deadlock)
Any abnormal condition will result in an abend. Conditions in this category include the following:
- I/O error
- A wait on storage (default action resulting from the short-on-storage condition) would result in a deadlock

The issuing program can request return of control with the COND to avoid a delay or an abend.

After completion of the #GETSTG request, the value in register 15 indicates the outcome of the operation:

Register 15 Value	Meaning
X'00'	The request has been serviced successfully.
X'04'	The request has specified a storage ID which did not previously exist; the indicated space has been allocated.
X'08'	The request cannot be serviced due to insufficient storage in the storage pool.
X'0C'	The request cannot be serviced due to an invalid parameter list.
X'10'	The requested storage cannot be allocated immediately (insufficient storage), and to wait would cause a deadlock.
X'18'	Allocated XA storage cannot be accessed by a 24-bit task. This situation occurs if storage is requested by STGID and the storage was initially allocated by an XA task.
