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 §
).
