When invoked as a conventional batch program, DFHCSDUP supports only one user exit: the EXTRACT exit, which is invoked at various stages during the processing of an EXTRACT command. The name of the user-written program to get control must be specified by the USERPROGRAM keyword of the EXTRACT command. Details of selected CSD objects are passed to the user exit program so that users can analyze the contents of their CSD in any way they may choose.
When invoked from a user program, DFHCSDUP supports the following five user exits, the addresses of which can be specified in the EXITS parameter of DFHCSDUP’s entry linkage:
For further information about these user exits, see the CICS® Customization Guide.
