The routine closes down history recording for the current application by writing default history information (when appropriate) to any NDFs which are still active, and by flagging that a new history record should be created to hold any subsequent history information (ready for the next application). If an application name has been declared via a call to NDF_HAPPN, then that name is cleared.

CALL NDF_HEND( STATUS )

STATUS = INTEGER (Given and Returned)

• This routine attempts to execute even if STATUS is set on entry, although no further error report will be made if it subsequently fails under these circumstances.

• This routine should not normally be used by writers of NDF applications. It is provided primarily to allow those writing environment-level software to identify the end of an application to the NDF_ system in circumstances where more than one application may be invoked from within a single executing program. Even then, it will not normally be needed unless NDF data structures are intended to remain open throughout the invocation of several applications and a separate history record is required from each application.
