For JES2, a “job” can actually be a batch job, started task, or time-sharing user (known as a job, STC, and TSU, respectively). They are further identified by a job identifier (jobid), which is an eight-character string of the form “JOBnnnnn”, “J0nnnnnn”, “STCnnnnn”, “S0nnnnnn”, “TSUnnnnn”, and “T0nnnnnn” respectively. You can control the action JES2 is to take on jobs, (for example, cancel, display, or hold), and you can control the display of information about jobs, as the following topics explain.
