RE: Second time updation of record within the same loop

[Jodi_Walker@xxxxxxxxxxxxxxxxxxx (Jodi Walker)]

     Or, easier yet, use the LEAVE op code - that takes you out of the loop 
     without any checking of the condition specified at DOU or DOW.
     
     C           *INLR     DOUEQ*ON
     C           'UB'      READEFILENAME                 LR C  NLR      
     COLDAT    IFGE BRDATE
     C****                     SETON                     LR C               
           LEAVE
     C                     ENDIF   
     C                     UPDATFILENAME
     C                     ENDDO
     
     i apologize if this is a double-post.  we seem to be experiencing 
     weirdness with our email system.

     Hoo-boy!  Hey guys, without getting into the religious war of DOU vs. 
     DOW in this situation, let's just help Dileep, OK?  
     
     Dileep, 
     
     In your choice of using DOU, you will have to code a "*INLR   IFNE 
     *ON" - "ENDIF" group.  The IF statement normally would go right after 
     your READx, and the ENDIF would go right before your ENDDO.  In your 
     case, though, since you have another condition that can set LR on, you 
     would place the *INLR IF right after that test.  As follows:
     
     C           *INLR     DOUEQ*ON
     C           'UB'      READEFILENAME                 LR C  NLR      
     COLDAT    IFGE BRDATE
     C                     SETON                     LR C                   
       ENDIF   
     C           *INLR     IFNE *ON
     *****
     C                     UPDATFILENAME
     C                     ENDIF
     C                     ENDDO
     
     Not directly related to your question, but I would strongly recommend 
     that you *not* use the plain END opcode; instead use the ENDIF, ENDDO, 
     ENDSL. Makes the code a little bit more readable.
     
     Don't know why you've got an endless loop on your pseudocode (I 
     presume this is a different problem than the actual code you 
     presented?).  If you've really got an endless loop, then your DOU 
     either is testing the wrong thing or the values that you're testing in 
     the DOU are not changing in the manner you expect them to.  Another 
     possibility - in this loop, are you adding records to the same file 
     you're testing for EOF?  Or maybe even updating a key value in the 
     record, causing it to "appear" again later in the access path?
