Controlling jobs and output

This describes the JES2 commands you use to start and stop jobs and to control the flow of work through the system and the network. It also describes the JES2 commands you use to control the output of jobs. These commands allow you to display job information.

The following tables list the tasks discussed in this and provide a cross reference to detailed descriptions of the corresponding commands.
