codes = range[2];
      let code = codes[0];
      for (j = 1, jj = codes.length; j < jj; ++j) {
        if (codes[j] !== codes[j - 1] + 1) {
          end = range[0] + j - 1;
          format31012 +=
            string32(start) + 
            string32(end) + 
            string32(code); 
          start = end + 1;
          code = codes[j];
        }
      }
      format31012 +=
        string32(start) + 
        string32(range[1]) + 
        string32(code); 
    }
    header31012 =
      "\x00\x0C" + 
      "\x00\x00" + 
      string32(format31012.length + 16) + 
      "\x00\x00\x00\x00" +

    "\x00\x04" + 
    string16(format314.length + 4) + 
    format314 +
