You can schedule temporary overrides to all Schedule Manager schedules by creating a schedule named @OVERRIDE@, which is a reserved name. The @OVERRIDE@ schedule is automatically merged into all other schedules when they are edited, and it is automatically merged into the ACTIVE schedule during RESET processing to set the desired states of resources.
The period names in the @OVERRIDE@ schedule are also reserved and are prefixed with the characters @OVER. You can only make changes to the @OVERRIDE@ schedule when editing it directly. If you try to modify @OVERRIDE@ period or link entries when editing another schedule, then your changes are rejected.
The following Links Control panel shows an example of an @OVERRIDE@ schedule to turn off all resources except JES2 for one hour every night at midnight. In this example, an L line command has been executed against the @OVER_MNIT period to display its links:
Schedule Manager ---------------- Links Control ----------------- System:OPS44R

The user deactivates the @OVERRIDE@ schedule by deleting it or renaming it.
Suppose, for example, that the sample @OVERRIDE@ schedule above was copied to a schedule named @OVERMNIGHT. Schedule @OVERMNIGHT could then be activated as the override schedule at any time by copying it or renaming it to schedule @OVERRIDE@.
