how can split Physical Address into the chunk and page on IDS 10 ?

Hello, how can I calculate maximum number of extents for a table? The documentation told me : Run the following oncheck option to obtain the physical address of the object (table or index fragment) for which you wish to calculate extent limits. oncheck -pt databasename:tablenameSplit the physical address of the table or index fragment into the chunk# (leading digits) and page# (last 5 digits), and then run oncheck -pP chunk# page#, specifying the arguments as hexadecimal numbers by prefixing with 0x. In Figure 29, the Physical Address is 7002c7. Therefore, chunk# is 0x007 (or 0x07) and the page# is 0x0002c (or 0x2c) in the following oncheck command: oncheck -pP 0x7 0x2c I am running $oncheck -pt bd_qbank_ghiseu:curs_valutar and get next results: TBLspace Report for bd_qbank_ghiseu:informix.curs_valutar Physical Address 3:606 Creation date 08/29/2005 08:00:59 TBLspace Flags 801 Page Locking TBLspace use 4 bit bit-maps Maximum row size 55 Physical Address : 3:606 How can split this address into the chunk and page ? It seems that address is not on hexadecimal format ... All Physical Address have the same format : 6:503130,6:503158...etc thank you
