Exit-related commands

In CICS, an exit is installation-supplied code that is invoked either at specific, CICS-defined points within CICS system code, or by an application request that uses the exit mechanism, such as a DB2 or IMS request.

There are two types: global user exits and task-related user exits. Global user exits are always invoked at CICS-defined points in system code; task-related exits can be invoked both ways. Customizing with user exit programs lists the points in CICS code at which global exits may be invoked, describes how and when task-related exits are driven, and gives full details for programming exits.

You can use them in any language supported by CICS, even though the exit itself must be coded in assembler.
