The following is an example of how various programs called by one monitor interact. Three example programs illustrate the operation of a message queue monitor. The message queue monitor is set up to monitor the QSYSOPR message queue for message ID CPI591A (Controller varied off or not recognized by local system). An interface exit program verifies that the line is active before starting the monitor. When the monitor receives message ID CPI591A, the condition program verifies that the line is active. The event program attempts to vary on the controller.
