Starting and stopping the service refresh cycle

The attention interrupt key (ATTN for SNA terminals and PA1 for non-SNA terminals) stops the cycle. When the cycle stops, the SERVICE REFRESH CYCLE application displays the service names, parameters, and any short messages for the cycled services. (Short message explanations can be viewed with Option M; for more information see MESSAGES option).

Each refreshed service display is shown in the sequence and time (DTIME) specified. For the example in SERVICE REFRESH CYCLE data entry display, the TASK application is displayed first, followed by PROBLEM and SUMMARY. The cycle repeats again, starting with TASK, until it ends with the pressing of the attention interrupt key, which displays the SERVICE REFRESH CYCLE application.
