Query/400 might not be installed. And "Embedded Query/400" isn't directly supported in most HLLs <g>. I'm sure others can add to the list. Even so, with a possible minor correction of a typo in the original SELECT, your Query/400 example should give the same result as the SQL example. The original SQL had A.DIVNUM = B.DIVNUM but the text of the post indicated it should be A.vendiv = B.DIVNUM That might've been an error only in the posted note, but if so, the correct SELECT would show only one side of the solution, I think -- it would only show rows in FILE1 that did not match any rows in FILE2. If I understand the problem, the complete solution might use UNION ALL to combine that SELECT with a second SELECT maybe like: SELECT * FROM FILE1 A EXCEPTION JOIN FILE2 B ON A.VENNUM = B.VENNUM AND A.vendiv = B.DIVNUM UNION ALL SELECT * FROM FILE2 C EXCEPTION JOIN FILE1 D ON C.VENNUM = D.VENNUM AND C.DIVNUM = D.vendiv and I'm not sure how this would easily be done with Query/400.
