Or, should I just continue to use ARs? Obviously you can use the hardware ARs of 1 and zero to move between primary and secondary. The advantage of MVCP/MVCSK, etc. are that they allow a move from a different key area while not in key0 to avoid overlays If you are planning a very big move it would be quite likely that your source will consist of multiple keys so if using MVCL in key0 be very very careful. -- Binyamin Dissen <[email protected]> http://www.dissensoftware.com Director, Dissen Software, Bar & Grill - Israel
