Defaults

If you do not specify the CLASS keyword, JES uses the installation default specified at initialization, as follows:

• In a JES2 system, the default is based on the source of the job: The system makes the job’s class the same as the installation-specified default class for the particular card reader, work station, or time-sharing user that submitted the job.
• In a JES3 system, the default is an installation-defined standard default class.
