!   This is the failure action routine called by the various

!
! FORMAL PARAMETERS:
!   function            - code which identifies the function that failed
!   primary_code        - primary completion code
!   secondary_code      - secondary completion code
!   nlb                 - address of the Network Link Block involved
!
! ROUTINE VALUE and
! COMPLETION CODES:
!   This routine returns the primary completion code as its completion code.
