NDF_CGET
- Obtain the value of an NDF character component
- Description:
The routine obtains the value of the specified character
component of an NDF (i.e. the value of the LABEL, TITLE or UNITS
component).
- Invocation:
CALL NDF_CGET( INDF, COMP, VALUE, STATUS )
- Arguments:
-
INDF = INTEGER (Given)
-
NDF identifier.
-
COMP = CHARACTER * ( * ) (Given)
-
Name of the character component whose value is required:
'LABEL', 'TITLE' or 'UNITS'.
-
VALUE = CHARACTER * ( * ) (Given and Returned)
-
The component's value.
-
STATUS = INTEGER (Given and Returned)
-
The global status.
- Notes:
-
If the requested component is in an undefined state, then the
VALUE argument will be returned unchanged. A suitable default
should therefore be established before calling this routine.
-
If the length of the VALUE argument is too short to
accommodate the returned result without losing significant
(non-blank) trailing characters, then this will be indicated by
an appended ellipsis, i.e. '...'. No error will result.
