Re: [COBOL400-L] reading a file organized by OPNQRYF

[MichaelQuigley@xxxxxxxxxx]

   If all you're doing is reading the file in the sequence generated by the
   OPNQRYF, then you should be able to code it for sequential organization
   and access.  Then you won't have to be concerned about the RECORD KEY
   clause.

   SELECT HISTRY4 ASSIGN TO DATABASE-HISTRY4
       ORGANIZATION IS SEQUENTIAL
       ACCESS MODE IS SEQUENTIAL
       FILE STATUS IS FILE-STATUS-01.

   Your open query file will hand the records to your COBOL program in HITEM,
   LMRKTC sequence.

   subject: [COBOL400-L] reading a file organized by OPNQRYF

   Just another quick question from a guy who'd really rather not have to
   fart
   around with this stuff.... :)   I'm converting a bunch of flat file FMTDTA
   stuff to use OPNQRYF instead.

   when reading a file in cobol that's been sorted via opnqryf, is there
   anything I need to worry about as far as COBOL syntax?

   this is what I have:

   OVRDBF     FILE(HISTRY4) SHARE(*YES)
   OPNQRYF    FILE((HISTRY4)) QRYSLT( +
                    'HPEROD *EQ ' *CAT &PERIOD *BCAT  +
               '*AND LMRKTC *NE "00" +
                *AND HITEM  *NE 0')   +
               KEYFLD((HITEM) (LMRKTC))

   and in my cobol:

   SELECT HISTRY4 ASSIGN TO DATABASE-HISTRY4
       ORGANIZATION IS INDEXED
       ACCESS MODE IS SEQUENTIAL
       RECORD KEY IS EXTERNALLY-DESCRIBED-KEY
       FILE STATUS IS FILE-STATUS-01.

   OPEN INPUT HISTRY4

   READ HISTRY4 AT END
    MOVE "Y" TO EOF-HISTRY4.

   CLOSE HISTRY4

   If I'm missing something obvious, I'd appeciate the heads up - I'm
   particularly concerned about the ACCESS MODE and RECORD KEY clauses of the
   SELECT Statement.  - indexed, sequential with external key - (not the
   file's natural key)

   I'm changing a ton of these, and I won't have a chance to test till I'm
   done, and I'd like to get it right the first time.

   Thanks a ton,

   Rick
