NDF_CLEN

Determine the length of an NDF character component

The routine returns the length of the specified character component of an NDF (i.e. the number of characters in the LABEL, TITLE or UNITS component).

CALL NDF_CLEN( INDF, COMP, LENGTH, STATUS )

NDF identifier.

Name of the character component whose length is required: ’LABEL’, ’TITLE’ or ’UNITS’.

Length of the component in characters.

The global status.

The length of an NDF character component is determined by the length of the VALUE string assigned to it by a previous call to NDF_CPUT (note that this could include trailing blanks).
If the specified component is in an undefined state, then a length of zero will be returned.
