NDF_STATE
- Determine the state of an NDF component (defined or undefined)
- Description:
The routine returns a logical value indicating whether an NDF
component has a defined value (or values).
- Invocation:
CALL NDF_STATE( INDF, COMP, STATE, STATUS )
- Arguments:
-
INDF = INTEGER (Given)
-
NDF identifier.
-
COMP = CHARACTER * ( * ) (Given)
-
Name of the component; any NDF component name is valid.
-
STATE = LOGICAL (Returned)
-
Whether the specified component is defined.
-
STATUS = INTEGER (Given and Returned)
-
The global status.
- Notes:
-
If a component name of 'EXTENSION' is given, then a .TRUE.
result will be returned if one or more extensions are present in
the NDF.
-
A comma-separated list of component names may also be given,
in which case the routine will return the logical "AND" of the
states of the specified components (i.e. a .TRUE. result will be
returned only if all the components have defined values).
