For processes started with a JOB command, $ZYJOBPARENT has pid of parent process
# Final Release Note
For processes started with the [JOB](https://docs.yottadb.com/ProgrammersGuide/commands.html#job) command, the [$ZYJOBPARENT(https://docs.yottadb.com/ProgrammersGuide/isv.html#zyjobparent) intrinsic special variable provides the pid of the process which executed the JOB command. For processes not started with the JOB command, $ZYJOBPARENT is 0. [#918]
# Description
Currently, the job command creates a CHILD job from a PARENT process, and the job number that is created is available from the PARENT as `$ZJOB`. However, from the CHILD job, it's impossible to know currently which PARENT M process spawned the CHILD. This issue is to remedy this.
# Draft Release Note
Added new ISV $ZYJO\[BPARENT\] to retrieve the PID of the process that created the current process with the JOB command.
If the current process was created with a JOB command, $ZYJOBPARENT will give the PID of the immediate parent who called the JOB command. If the current process was not invoked with a JOB command, $ZYJOBPARENT will be 0. The abbreviation for $ZYJOBPARENT is $ZYJO.
Example
```
$ cat jobPID.m
w "JOB from parent:",$JOB,!
w "ZYJOBPARENT from parent:",$ZYJOBPARENT,!
job NEXT
quit
NEXT
w "ZYJOBPARENT in child:",$ZYJOBPARENT,!
quit
$ $ydb_dist/yottadb -run jobPID
JOB from parent:26772
ZYJOBPARENT from parent:0
$ cat jobPID.mjo
ZYJOBPARENT in child:26772
$
```
