XIB exit interface block for connections to IMS TM

IMS Connect provides the XIB exit interface block to support the processing of IMS Connect user message exit routines that are used when connecting to IMS TM. You can use the XIB exit interface block and the user area it includes to store information that is used by your exit routines.

IMS Connect stores the following types of information in the exit interface block:

• Information about the XIBDS.
• Information about the IRM architecture level used.
• User data.

You can also use the XIB_USERAREA field of an exit interface block for any purpose. You can code the IMS Connect User Initialization exit routine (HWSUINIT) or your IMS Connect user message exit routine to use the XIB_USERAREA field.

The exit interface block is mapped by the HWSXIB macro.
