Oracle Ref Cursor and ADO Express

Does anyone have any experience in working with stored procedures in Oracle
that return REF CURSORs as out parameters?  This is a new feature in
Oracle's OLE DB provider for 8.1.6, and I cannot get it to work with either
TADOCommand ot TADOStoredProc.

I have examples of working Visual Basic code, but my translation of that
code does not work.  I am worried that, since Delphi's implementation of ADO
is completely different than Visual Basic's, Oracle REF CURSORs are not
going to work.
