Deleting NDFs   

Deletion of an NDF may be performed by calling the routine NDF_DELET, thus:

      CALL NDF_DELET( INDF, STATUS )

If the necessary access is available (see §[*]), the associated data structure will be erased and a value of NDF__NOID will be returned for the INDF argument. Any other identifiers associated with the same data structure will also become invalid at this point. Note that deletion cannot be performed via an identifier which refers to an NDF section. In this case, NDF_DELET will simply annul the identifier as if NDF_ANNUL had been called (see §[*]).
