Determine if the entire system is hung up or just one job. Try to do something at another workstation. Try the attention function. (on a PC this is the ESC key).  On the console this is the Shift and System Request key.  You will get a line at the bottom of the screen that will allow you to press the enter key.  Option 2 will try to end your current job ( or request), option 3 wil display your job, option 6 will display system operator messages.

If a single job is hung up, decide what to do based on the status of the job and its function. You can use the Work with Active Jobs (WRKACTJOB) command to watch the job and see if it is hung up or in a continuous loop (when you use the refresh function, does the status change?). Check for messages about the job. You may need to end the job, which you can do from the Work with Active Jobs (WRKACTJOB) command. You can also end a job by using the End Job (ENDJOB) command or the End Job Abnormal
(ENDJOBABN) command.

If your entire system is hung up, you probably need help from the support desk. Collect the following information before you call so that we can help you more quickly:

Observe the processor light on the system unit for a few minutes. Is it blinking frequently, infrequently, or a solid light?
Is the attention light on the system unit lit?

Are there codes (SRCs) displayed on the control panel? If yes, write down the codes. Use the select button on the control panel to display additional codes.
