NDF_BASE - Obtain an identifier for a base NDF   

Description:
The routine returns an identifier for the base NDF with which an NDF section is associated.

Invocation:
CALL NDF_BASE( INDF1, INDF2, STATUS )

Arguments:
INDF1 = INTEGER (Given)
Identifier for an existing NDF section (the routine will also work if this is already a base NDF).
INDF2 = INTEGER (Returned)
Identifier for the base NDF with which the section is associated.
STATUS = INTEGER (Given and Returned)
The global status.

Notes:
  • 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.
