Before processing SMP/E commands, you must first set the zone on which you want SMP/E to work (global, target, or distribution). You do this by issuing the SET command. The SET command identifies the zone and, therefore, the libraries, upon which subsequent SMP/E commands are to act.

The SET command can also be used to request a particular set of predefined processing options. For more information about the SET command, see SMP/E for z/OS Commands.
