This causes the JOBNAM subroutine to return the name of the parent job rather than the current job, when the current job was launched via the AMOS subroutine and the AMOS_RUNSBR switch is not active. This mimics one aspect of the way XCALL AMOS worked under AMOS (i.e. that the child process was still the original job.) Note that under A-Shell, the child process is truly a separate job and thus cannot share any memory based information, unless the AMOS_RUNSBR switch is active, which see above.
