Jim,

>FROM ves!master2 LEFT OUTER JOIN arcadr01 ;
ON Master2.custno + Master2.cshipno = Arcadr01.custno + Arcadr01.cshipno

this only applies if all fields are caracter. If they're numeric you can get unexpected results. If all the mentioned fields are indexed it's maybe better to use

FROM ves!master2 LEFT OUTER JOIN arcadr01;
LEFT OUTER JOIN ves!master2 ;
ON Master2.cshipno = Arcadr01.cshipno AND Master2.custno = Arcadr01.custno ;
