Hi, Everybody

       Array (

       [MAIN_CODE] => MAINTEST1
       [SUB_CODE] => SUBTEST1
       [MAINCODE_STATUS] => N

           )
[1] => Array (

       [MAIN_CODE] => MAINTEST1
       [SUB_CODE] => SUBTEST2
       [MAINCODE_STATUS] => N

               Array(
                   MAINCODE_STATUS => N
                   SUBTEST1 =>
                           Array(
                               SUBCODE_STATUS => N
                               CODE_TEST => YES
                                 )
                   SUBTEST2 =>
                           Array(
                              SUBCODE_STATUS => N
                              CODE_TEST => NO
                                )

                      )
