Use the CEEWCXIT sample job to change the CICS® installation-wide assembler language user exit. You must replace the comment in CEEWCXIT with your source for CEECXITA. You can copy the source for the IBM-supplied default installation-wide assembler language user exit from CEECXITA in CEE.SCEESAMP and modify it to suit your needs, or you can create your own source for CEECXITA.

Note the difference between the IBM-supplied CEEBXITA and the IBM-supplied CEECXITA. You can retain some or all of these differences in your user exit. Use the information in z/OS Language Environment Programming Guide to guide you in coding your changes.

To modify the JCL for CEEWCXIT:

1. Replace the comment lines following the ++ SRC statement in the job with your source program for the installation-wide CICS 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.

CEEWCXIT should run with a condition code of 0.
