Type-1 Automated Operator Interface enhancement for 31-bit storage support

For IMS 15, the Type-1 Automated Operator Interface (AOI) exit routine interface module is enhanced to support obtaining 31-bit private storage from the Automated Operator Interface buffer pool (AOIP).

To pass information to the DFSAOUE0 exit routine, the AO exit routine interface module is modified to obtain 31-bit private storage from the AOI buffer pool, instead of obtaining 24-bit private storage from the communication I/O buffer pool (CIOP). If available space is not sufficient in the AOI buffer pool, the new DFS3458 message is issued.

Migration considerations

IMS 15 and later systems obtain the user exit header block (UEHB) and any additional buffers that are passed to the DFSAOUE0 exit routine from 31-bit private storage.
