The program you specified is already being edited by another user.Therefore, you can access it only in display mode.

• Check that you are not already editing the program in another mode and,
if necessary, switch to that mode.

finished. Usually, the lock is set only for a short time.

• If you cannot wait, contact the user whose name is displayed in this
message.
