NDF_EXIST

See if an existing NDF is associated with an ADAM parameter

Description:

The routine determines if an existing (and accessible) NDF is associated with an ADAM parameter. If it is, then an identifier is returned for it. If not, then the routine returns with an identifier value of NDF__NOID; this then allows the NDF structure to be created (e.g. using NDF_CREAT) if required.

Invocation

CALL NDF_EXIST( PARAM, MODE, INDF, STATUS )

Arguments

PARAM = CHARACTER ( ) (Given)
Name of the ADAM parameter.
MODE = CHARACTER ( ) (Given)
Type of NDF access required: READ, UPDATE or WRITE.
INDF = INTEGER (Returned)
NDF identifier.
STATUS = INTEGER (Given and Returned)
The global status.
