13% when Param.Action.RUN=0 (as activated when the current Action is selected
14% in series), the function ouput paramOut set the activation of the needed GUI elements
15%
16% Param contains the elements:(use the menu bar command 'export/GUI config' in series to
17% see the current structure Param)
