     Or, yet another way. Since DOU checks at the bottom of the loop, and 
     assuming that the date check is an attempt to prevent the second loop. 
                    
          
     C           'UB'      READEFILENAME                 LR
     C*
     C           *INLR     DOUEQ*ON
     C  NLR      COLDAT    IFLT BRDATE
     C           *INLR     ANDNE*ON
     C                     UPDATFILENAME
     C           'UB'      READEFILENAME                 LR
     C                     ENDIF   
     C                     ENDDO
     
     If you coded with a leading decision loop, DOW, I find it cleaner:
     
     C           'UB'      READEFILENAME                 LR
     C*
     C           *INLR     DOWEQ*OFF    
     C  NLR      COLDAT    IFLT BRDATE
     C                     UPDATFILENAME
     C           'UB'      READEFILENAME                 LR
     C                     ENDIF   
     C                     ENDDO
     
     If the date check is indeed an attempt to prevent the second loop, 
     then it isn't needed and becomes even cleaner
     
     C           'UB'      READEFILENAME                 LR
     C*
     C           *INLR     DOWEQ*OFF    
     C                     UPDATFILENAME
     C           'UB'      READEFILENAME                 LR
     C                     ENDDO
     And this code fits the original psuedocode as posted, accomplishing 
     the do until end of file portion using a DOW. I imagine this is an 
     effort at avoiding 'negative coding' that is, do until end of file as 
     opposed do while not end of file.  This can lead to choosing the 
     'wrong' op code. Semantics. Gotta love 'em.
     > DOU end of file.
     > Read the file.
     > If record is valid.
     > Search for matching record in some other file.
     > If search is successful, update records in file. > EndDo
