WORLD is a privilege that allows a process to affect other processes both inside and outside its group by executing the following process-control system services:

The user's process is also allowed to examine processes outside its own group by executing the Get Job/Process Information ($GETJPI) system service. A process with WORLD privilege can issue the SET PROCESS command for all other processes. Any process with WORLD privilege can also obtain information about a lock held by a process in another group using the Get Lock Information ($GETLKI) system service.

To exercise control over subprocesses that it created or to examine these subprocesses, a process needs no special privilege. To affect or examine other processes inside its own group, a process needs only the GROUP privilege. This privilege should only be granted to users who need to affect or examine processes outside their own group.
