Unimplemented

The Unimplemented procedure triggers a system error when called.

PROCEDURE Unimplemented;

DESCRIPTION

The address of the Unimplemented procedure is at system startup time placed into all entries of each trap dispatch table that do not contain an address of a system software routine. When called, the Unimplemented procedure triggers the system error 12, dsCoreErr, which crashes the currently running application.

WARNING

Your application should never use this procedure.
