The routine produces a "cloned" copy of an NDF identifier (i.e. it produces a new identifier describing an NDF with identical attributes to the original).

CALL NDF_CLONE( INDF1, INDF2, STATUS )

INDF1 = INTEGER (Given)

INDF2 = INTEGER (Returned)

STATUS = INTEGER (Given and Returned)

• If this routine is called with STATUS set, then a value of NDF__NOID will be returned for the INDF2 argument, although no further processing will occur. The same value will also be returned if the routine should fail for any reason. The NDF__NOID constant is defined in the include file NDF_PAR.
