Joe- Perhaps an approach that combines your idea and mine. The getColumn() method returns an Object, then another program takes the object and calls the "instanceOf()" method to find out the actual class, then it fills in the data structure that you proposed. Then passes a pointer to the populated datastructure back. Using this combined approach, the "getColumn()" method doesn't have to deal with populating the datastructure. It would also simplify error handling. If the "instanceOf" method returns something that is not usable from RPG, then the Java program can throw/log an exception. -Sarah Poger Gladstone
