Inhibiting Component Propagation

Conversely, if any of the standard NDF components which are propagated by default would be rendered invalid by the processing an application performs, then propagation may be inhibited by specifying the component name with the prefix `NO' in the CLIST argument to NDF_PROP. For instance:

      CALL NDF_PROP( INDF1, 'Quality,NoLab', 'OUT', INDF2, STATUS )

would force propagation of the quality component, but inhibit the default propagation of the label component.
