If a process is taking a program dump, then this fact is reflected in the Stack State display of the Y (Status Interrogate) system command. The following example shows the output from the Y command for a process that is taking a dump:

Status of Task 6408/6513 at 16:39:09
Program name: *OBJECT/ED ON SYS00
Priority: 50
Origination: OCDWH_1/CANDE/2  (LSN 295)
MCS: SYSTEM/CANDE
Usercode: DEBS
Chargecode: 6893
Stack State: Waiting on an event, Programdumping
Display: ED:OPERATOR DSED @ (47312200)

This command can be useful, for example, if you have entered a DS (Discontinue) system command for a process, and the process seems to be taking a long time to terminate. By entering the Y command, you can determine whether the delay is caused by a program dump. You can then enter a second DS command if you wish to discontinue the program dump.
