The DCB abend installation exit gives your installation an additional option for handling error situations that result in an abend. This exit is taken any time an abend condition occurs during the process of opening, closing, or handling an end-of-volume condition for a DCB. An IBM-supplied installation exit routine gives your installation the option to retry tape positioning when you receive a 613 system completion code, return code 08 or 0C. For more information about the DCB abend installation exit, see z/OS DFSMS Installation Exits.
