Figure 4. A Job in the Integrated Language Environment
In the description that follows, the reference keys refer to the corresponding
reference keys in Figure 4.
In the integrated language environment, overrides can be scoped to the call level,
the activation-group level (the default), and the job level. A job is a piece of work
that the system performs. An interactive job begins when a user signs on and ends
when a user signs off. Overrides (A) that are scoped to the job level have affect on
all programs that are running in any activation group within the job. There can be
only one active override for a file at the job level. If you specify more than one, the
most recent one takes effect. An override that is scoped to the job level remains in
effect until one of the following occurs:
v The job ends
v The system explicitly deletes the override
v Another job level override for the same file replaces the override
This is true regardless of the call level in which the overrides were specified. For
example, an override that is issued in call level 3 that is scoped to the job level
remains in effect when call level 3 is deleted. Overrides can be scoped to the job
level by specifying OVRSCOPE(*JOB) on the override command.
Overrides (B) that are specified in the user default activation group can be scoped
to the call level or to the job level. They cannot be scoped to the user default
