Output

When the storage access service returns control to your exit routine, field ADPLPART contains the address of the buffer containing the requested data, if the processing was successful. Register 15 contains one of the following return codes:

Code: Meaning
00: The storage was accessed successfully
04: The requested storage was not in the dump or the service was unable to access the storage.

Note:

Your exit routine must test the contents of register 15.
Your routine must use the data in the buffer to which ADPLPART points before the routine makes another call to an IPCS service. The reason is that the buffer contents are changed by a call to the storage access service and might be changed by a call to another IPCS service.
