Summary
NOTE: This procedure is supported for compatibility with previous software and should not be
used for new development.
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' process control block extension with the four-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.)
Figure 10 (page 1395) illustrates the effect of STEPMOM.

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This procedure does not have a C syntax, because it is superseded and should not be used for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.
