>>>Didn't get to it yet. I teach an ASP class Monday and Wednesday nights and sometimes get just too tied up. Hopefully tonight. But you are on the right track (or at least the track I was going to pursue. Pass the SQL statement to an object, execute the statement in the object to save the data to an array. Provide methods to access a record (row), like MoveFirst, MoveLast, MoveNext, MovePrevious, etc. Events to DELETE, ADDNEW, etc. just like ADO, but using an object that contains the data as an array.

It is probably not a big deal. We can use AFIELDS() to get the cursor structure into another array property and then CREATE FROM ARRAY and populate the cursor from the another array property which contains data. (Didn't test it yet though.)
