Installing the exit

Install the load module that contains the exit into an APF-authorized library. ICSF uses this normal z/OS search order to locate the exit:
Define the ICSF name and load module name on the EXIT keyword in the installation options data set. For more information about the installation options data set, see Parameters in the installation options data set. The EXIT keyword has this syntax:
The ICSF name portion of the keyword refers to the ICSF name for the exit. The ICSF name for the conversion program exit is CSFCONVX. The load module name is the name of the load module that contains the exit. This name can be any valid name that your installation chooses. The FAIL portion of the EXIT keyword specifies the action ICSF takes if the exit cannot be loaded. The valid FAIL options are NONE, EXIT, SERVICE, and CSF. For the conversion program exit, you can use these options only:
NONE
Initialization continues even if exit cannot be loaded.
ICSF
Initialization ends if exit cannot be loaded.

You must specify a FAIL option. If you do not, ICSF returns an error message, ends abnormally, and generates an SVC dump when attempting to load the exit.

If the exit ends abnormally, the conversion program does also.
