Guidelines
Disabling the UNDO command before making massive changes improves the response time and avoid exceeding available memory. The alternative for discarding your unwanted changes is the CANCEL command.
The setting for change recording is saved in your File-AID edit profile from session to session. Use the PROFILE primary command to display its current setting.
