To make it easier to control and identify jobs on the system, each job has a unique qualified job name. The qualified job name consists of three parts: the job name (or simple job name), the user name, and the job number.
WRKJOB JOB(000578/QPGMR/DSP01)
orWRKJOB JOB(QPGMR/DSP01)
WRKJOB JOB(DSP01)
This works the same as entering the entire qualified job name. If several jobs on the system match the portion of the job name that you entered, the Select Job display appears. This display allows you to select which job you want from a list of duplicate job names.
