ADO Express and Oracle REF CURSORS

How do I return Oracle REF CURSORS from oracle stored procedures using ADO
Express ? I've got examples of working code in Visual Basic (provided with
Oracle 8.1.6 docs) but my transalation of that code to Delphi does not seem
to work. Since Delphi's implementation of ADO seems to be completely
different from that of VB , I am very worried that it is not going to work.
I am using Oracle 8.1.6 , Delphi 5 EE with the update pack.
