This parameter specifies the name of the user-written interface that communicates with Connect:Direct® for z/OS®. You can invoke the allocation exit prior to any allocation activity by IBM® Connect:Direct, thereby allowing the exit program to examine and modify information that IBM Connect:Direct uses during the allocation Process, such as the data set name (DSN) and destination name. In addition, you can set parameters to terminate a copy step before allocation takes place.

For sample exits, see the $CD.SDGASAMP library. The default is no allocation exit.

Modifiable through MODIFY INITPARMS command: NO
