Summary
The STEPMOM procedure is called by a process when it wants to receive process
deletion (STOP or ABEND) messages for a process it did not create. Note that the
caller of STEPMOM becomes the new “mom” of the designated process. (That is,
STEPMOM replaces the mom field in the designated process’s process control block
extension with the 4-word process ID of its caller.) Therefore, only the caller receives
the process deletion notification.
STEPMOM is typically used by the backup process of an unnamed process pair to
monitor its primary process. (This monitoring is automatic between members of
named process pairs.)
Syntax for C Programmers
This procedure does not have a C syntax, because it is superseded and should not be
used for new development. This procedure is supported only for compatibility with
previous software.
Syntax for TAL Programmers
Note. This procedure is supported for compatibility with previous software and should not be
used for new development.
