Hi Cindy,

LEAVE would get you out of the infinite loop, but the burning question is,
when? You only want to get out when the subsystem is shutting down or an
operator has requested a shutdown, which is what the SHTDN opcode tells you:

The SHTDN operation allows the programmer to determine whether the system
operator has requested shutdown. If the system operator has requested
shutdown, the resulting indicator specified in positions 71 and 72 is set
on. Positions 71 and 72 must contain one of the following indicators: 01
through 99, L1 through L9, U1 through U8, H1 through H9, LR, or RT.

The system operator can request shutdown by specifying the *CNTRLD option on
the following CL commands: ENDJOB (End Job), PWRDWNSYS (Power Down System),
ENDSYS (End System), and ENDSBS (End Subsystem). For information on these
commands, see the CL Reference (Abridged).

Regards,
Peter Dow
