        'Display window');
    lbh = uicontrol(ph,'style','listbox','Units','normalized','position',...
        [0 0 1 1],'FontSize',9);

    indic = 1;
    while 1
         tline = fgetl(fid);
         if ~ischar(tline), 
             break
         end
         strings{indic}=tline; 
         indic = indic + 1;
    end
    fclose(fid);
    set(lbh,'string',strings);
    set(lbh,'Value',1);
    set(lbh,'Selected','on');
