You can use the Display Override (DSPOVR) command to display file overrides at the job level, the activation group level, and at multiple call levels for a job. You can display all file overrides or overrides for a specific file.
The file overrides can be merged before being displayed. A merged override is the result of combining overrides from the job level to the current level or any specified call level, producing a composite override which will be applied when the file is used at the specific call level. The current call level is the call level of the program that is currently running. This program is the last program name that is displayed on the call stack. This command can be requested from either a batch or interactive environment. You can also access this function from option 15 (Display file overrides) from the Work with Job menu (using the WRKJOB command) or by selecting option 15 (Display file overrides) from the Display Job menu (using the DSPJOB command).
