SHTDN				ON	_	_

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 IBM® i Information Center programming category.

Positions 73 through 76 must be blank.

For more information, see Information Operations.
