Using Your Routine for Only Certain Jobs

If you plan to have your routine invoked for only certain jobs, give it a unique name, and install it in SYS1.LINKLIB or an authorized library concatenated to LINKLIB through a LNKLSTxx member of SYS1.PARMLIB. To have your routine invoked, the end-user must specify its name on the SYSOUT= parameter of the job's DD statement. When your routine is not specified, the system calls the IBM-supplied routine by default.
