The Default Schedule Command attribute indicates the command of the Schedule object when no event is in effect, due to no scheduled command or a conscious gap in the schedule. The Default Schedule Command is executed every midnight unless another event is in place to begin at midnight.
The Default Schedule Command also supports the Release command. The Release command releases the Scheduling function’s control of the scheduled objects. Setting the Default Schedule Command to Release is the only available method to release the schedule’s control of scheduled objects through the Schedule object. Release should only be used for the Schedule Default Command if the scheduled items support the Release command.
