Thanks for all of the replies.  (except Pat for the "MR" solution -just
kidding-)  Although, since the solution requires random access, "MR"
wouldn't have worked anyway.

Three of you suggested SQL.  Can I presume it can't be done with LF DDS?

Also, I noticed the difference between Scott's solution:
   SELECT (list of fields) FROM FILE1
     EXCEPTION JOIN FILE2
     on (file1 field) = (file2 field)

and Rob's and "ubhalla"'s solution:
   SELECT  *  FROM  FILEA WHERE ITEM# NOT IN (SELECT ITEM# FROM FILEB)

Do I care about the difference between using "EXCEPTION JOIN" and "WHERE
ITEM# NOT IN (SELECT ...)"?????  Are there performance or other factors?

Thanks again!
- Dan Bale
