def output_array(s)
    str = ''
    if s.is_a?(Array)
       if s.length >= 1
          str = s.at(0)
          str = "\"#{str}\""
          if s.length > 1
             for i in 1..(s.length - 1)
                 w = s.at(i)
                 str = "#{str}, \"#{w}\""
             end
          end
