  Text:         'LOCK' clause specified for 'EXCLUSIVE' file
 
  Explanation:  You have specified a LOCK clause in a READ statement
                for a file that you have already locked with an
                EXCLUSIVE lock (in the FILE-CONTROL paragraph of your
                code).
 
  Resolution:   Record locking is impossible on a file which your run
                unit has already locked with an EXCLUSIVE lock.  To
                ensure that the two LOCK entries are compatible, you
                will have to either delete the LOCK entry in the
                relevant READ statement, or alter the LOCK MODE IS
                entry in the FILE-CONTROL paragraph.
