JES2 automatically starts local card readers if you specify the START=YES parameter on the RDR(nn) JES2 initialization statement. The operator can then enter job streams into the system by placing the cards in the hopper and pressing the start button on the reader; the operator does not have to issue a JES2 start ($S) for the reader. The operator deallocates the card reader from JES2 by issuing the JES2 stop ($P) reader command.
