Since I'm a big fan of LIKEDS, I'd convert the data structure to a
"template" (a structure that's just used as a template for creating other
data structures) and then I'd create a copy that's all zeroes to compare
to.

The following code should give you the idea:

     DBrnTotal_t       DS                  QUALIFIED
     D BTAM59                              LIKE(CMAM22) INZ(0)
     D BTAM01                              LIKE(CMAM01) INZ(0)
     D BTAM02                              LIKE(CMAM02) INZ(0)
     D BTAM03                              LIKE(CMAM03) INZ(0)
     D BTAM04                              LIKE(CMAM04) INZ(0)
     D BTAM05                              LIKE(CMAM05) INZ(0)
     D BTAM06                              LIKE(CMAM06) INZ(0)
     D BTAM07                              LIKE(CMAM07) INZ(0)
     D BTAM08                              LIKE(CMAM08) INZ(0)
     D BTAM09                              LIKE(CMAM09) INZ(0)
     D BTAM10                              LIKE(CMAM10) INZ(0)

     DBrnTotal         ds                  likeds(BrnTotal_t)
     D                                     dim(999)
     D                                     inz(*LIKEDS)

     DBrnZeroes        ds                  likeds(BrnTotal_t)
     D                                     inz(*LIKEDS)

      /free

          For Brn = 1 to %elem(BrnTotal);
              if (BrnTotal(Brn) <> BrnZeroes);
                 // do something with subfileds
              endif;
          endfor;

      /end-free
