Use a cursor.
lparameters taCodeList
create cursor crsItems (itemcode c(10))
dimension taCodeList[alen(taCodeList),1]
insert into crsItems from array taCodeList

SELECT Test.code, Test.Desc ;
 FROM Test ;
   inner join crsItems itm on test.code == itm.itemcode ;
   INTO CURSOR result
use in 'crsItems'
