You can customize Language Environment by either tailoring and installing IBM-supplied usermods, or by tailoring and running specific jobs.

To tailor and install usermods:

1. Get the list of usermods that suit the programmer needs at your site. This topic will help you create this list.
2. Copy the customization jobs from the SCEESAMP data set into one of your private data sets so you will have unmodified copies of the jobs for your later reference and use.
3. Apply the usermods to the target libraries, but do not accept them, and do not modify the distribution libraries.
4. Use SMP/E RESTORE to remove a usermod if necessary (for example, if programming needs at your site change) or before you apply service to the modules it changes.
5. Reapply the usermod after successful installation of service.

To modify the JCL for customization jobs:

1. Copy the customization jobs from the SCEESAMP data set into one of your private data sets so you will have unmodified copies of the jobs for your later reference and use.
2. Add a job card appropriate for your site.
3. Add a JES Route card if your site requires one.
4. Modify the job according to the comments in the JCL or the instructions in this information.
5. Save and submit the job.
6. Most jobs will run with a condition code of 0. Check the description of each job to find out what condition code to expect. If the job did not run with the condition code you expected:
   • Check for an error message on the system console or the list output to find the cause of the problem.
   • Correct the problem.
   • Rerun the job.
   • Recheck the condition code.
