Use the CEEWDXIT sample job to change the installation-wide assembler language user exit. You must replace the comment in CEEWDXIT with your source for CEEBXITA. You can copy the source for the IBM-supplied default installation-wide assembler language user exit from CEEBXITA in CEE.SCEESAMP and modify it to suit your needs, or you can create your own source for CEEBXITA. Use the information in z/OS Language Environment Programming Guide to guide you in coding your changes.

To modify the JCL for CEEWDXIT:

1. Replace the comment lines following the ++ SRC statement in the job with your source program for the installation-wide assembler language user exit.
2. Change #GLOBALCSI to the data set name of your global CSI data set.
3. Change #TZONE to the name of your target zone.
4. Add necessary SMP/E PRE information for PTFs you have installed on your system which contain the same part.

CEEWDXIT should run with a condition code of 0.
