I wonder how much performance improvement can be done by reducing the code path for OPEN. OPEN has to access the media to read labels, after all. -- Binyamin Dissen <[EMAIL PROTECTED]> http://www.dissensoftware.com Director, Dissen Software, Bar & Grill - Israel Should you use the mailblocks package and expect a response from me, you should preauthorize the dissensoftware.com domain.
