Example remove_watchdogs( _, account ) . Clear the workspace of all instances, slot values, all facts and all exceptions, re-enable all rules and finally run all data directives. It is defined by the program: restart :- remove_instances, remove_slots, remove_facts, remove_exceptions, enable_rules, run_data. Invoke the actions associated with all data directives. If any action fails then a message to indicate this is written to the current output stream. run_data( +Name ) Invoke the action associated with the data Name. If the action fails then a message to indicate this is written to the current output stream. Example run_data( start_up_configuration ) . some_instance( +Name,?Element ) Retrieve (or check) an Element which is an instance of Name.
