NDF_CLEN - Determine the length of an NDF character component

Description:
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).

Invocation:
CALL NDF_CLEN( INDF, COMP, LENGTH, STATUS )

Arguments:
INDF = INTEGER (Given)
NDF identifier.
COMP = CHARACTER * ( * ) (Given)
Name of the character component whose length is required: 'LABEL', 'TITLE' or 'UNITS'.
LENGTH = INTEGER (Returned)
Length of the component in characters.
STATUS = INTEGER (Given and Returned)
The global status.

Notes:
  • 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.
