Date not valid, V7R1 Dynamic SQL

I have a field in a file defined as a date data type, *ISO. I display the date on the screen in *USA format. The problem comes when trying to retrieve the record via a subfile built thru SQL. I get no record due to the date being invalid because the date is 2099-12-01. According to the RPG & DDS books, date in either USA or ISO formats can go to 9999 in the year. If I change the date to 2039, the record is retrieved perfectly.
