A WFL job automatically restarts if interrupted by a halt/load. WFL is the only language with this automatic restart capability. WFL also plays an important role in the restarting of checkpointed processes. These processes must be offspring of a WFL job in order to be checkpointed. In addition, the WFL RERUN statement is the means used to restart a checkpointed process. For further information, refer to Restarting Jobs and Tasks.
