Al, Office2007 isn't 64-bit either. Time to abandon Office, right? ;-)
Take a look at that
www.etecnologia.net company that is creating a VFP NET compiler. They provide dbf access using a separate mechanism that (amongst other things) allows more than 255 fields per table and dbfs of more than 2Gb. By the time Office2007 is rewritten as a 64-bit app, there will be plenty of 64-bit options to keep using dbfs or transfer them to a different store if that makes sense. Actually the way things are going, people might decide it is better to use one of the other free backends that offer better scalability and security.
"... They ne'er cared for us
yet: suffer us to famish, and their store-houses
crammed with grain; make edicts for usury, to
support usurers; repeal daily any wholesome act
established against the rich, and provide more
piercing statutes daily, to chain up and restrain
the poor. If the wars eat us not up, they will; and
there's all the love they bear us."
-- Shakespeare: Coriolanus, Act 1, scene 1
