activation group level. However, overrides (C and D) that are specified in a named<br />
activation group can be scoped to the call level, activation group level, or the job<br />
level. Overrides (C) scoped to a named activation group level remain in effect until<br />
the system replaces or deletes the override, or until the system deletes the named<br />
activation group.<br />
Overrides (D) that are scoped to the call level within a named activation group<br />
remain in effect until they are replaced, deleted, or until the program in which they<br />
were issued ends. Overrides can be scoped to the call level by specifying<br />
OVRSCOPE(*CALLLVL) on the override command.<br />
Overrides that are scoped to a named activation group level apply only to<br />
programs that run in the named activation group. They have no affect on<br />
programs that run in other named activation groups or in the user default<br />

one program calls another program within a job. Overrides that are scoped to the<br />
call level remain in effect from the time they are specified until they are replaced,<br />
or deleted, or until the program in which they are specified ends. This is true<br />
whether you issue the override in the user default activation group or in a named<br />
activation group.<br />

Several commands, such as Work with Job (WRKJOB), Work with Active Jobs<br />
(WRKACTJOB), or Display Job (DSPJOB), have options that allow you to display<br />
the call stack of an active job. There is a one-to-one relationship between a<br />
program that is displayed in the call stack and the call level. The first program
