AUTORELBLOCKADDRESS specifies that direct access data sets be automatically processed by relative block address rather than by track-track-record (TTR). The data sets must be accessed with an optional services code (OPTCD) setting. This setting indicates the data sets are organized by relative block address.

Note:

If any such data set is actually organized by TTR, the data set might become unusable.
The TTRADDRESS keyword takes precedence over the AUTORELBLOCKADDRESS keyword. Refer to the RELBLOCKADDRESS and TTRADDRESS keywords for more information.
AUTORELBLOCKADDRESS is ignored for direct access data sets with variable-spanned record formats or standard user labels.

For more information about the OPTCD, see z/OS DFSMS Macro Instructions for Data Sets.
