I ran a DBMS_SCHEDULER.CREATE_JOB from the Toad Editor. When I tried to access the script again from the Schema Browser | Sched. Jobs | Script tab, Toad is showing an incorrect script where the 'number_of_arguments' parameter is missing and the 'argument_position' parameter in SET_JOB_ARGUMENT_VALUE is missing.
WORKAROUND: None
STATUS: Waiting for fix in a future release of Toad for Oracle
