Database File I-O

Cobol Newbie question...........

I am reading files created thru DDS in an RPG environment.
When the COPY command is executed during my ILE Cobol compile, I get the following: 

*THE KEY DEFINITIONS FOR RECORD FORMAT TFOOD00
*   NUMBER       NAME               RETRIEVAL          ALTSEQ
*     0001             ODORG             ASCENDING           NO
*     0002             ODTOOR           ASCENDING           NO
*     0003             ODTOLN           ASCENDING           NO
           05   TFOOD00.
                   06  ODORG                               PIC X(3).
06 ODPLN PIC S9(9) COMP-3. 
                   06  ODSWHS                            PIC X(3).
                   06  ODORTP                             PIC X(3).
                   06  ODTOLN                             PIC S9(7) COMP-3.
                   06  ODTOOR                             PIC S9(9) COMP-3.
                   06  ODSHOR                             PIC S9(9) COMP-3.
                     ..... etc ....
I have another file, TFOOH, that is the 'driver' file. Once I find a record in the TFOOH, I then want to access all the associated records in the TFOOD. I have OHORG and OHTOOR fields in the TFOOH which can be used to point to the correct set of records in the TFOOD.
My question is, how do I do a START on the TFOOD file, so that I am positioned to the 1st record I want. 

If I had defined the file myself, I would have a key setup as:

                   06  TFOOD-KEY.
                         07  ODORG                               PIC X(3).
07 ODTOOR PIC S9(9) COMP-3. 07 ODTOLN PIC S9(7) COMP-3. 

Then I could populate the 1st 2 fields and do a START NOT < TFOOD-KEY.
But since these are not group, how do I do it in ILE COBOL?
I do not want to START on the ORORG and READ until I finally get a hit.... there are 10000s of records. 

Thanks for any help!!!
