In some cases, 64 bits won't buy you anything and may in fact run slower than 32 bit. You really only need to go to 64 bits if you have large memory needs.

>This is the standard of all our projects. Some of the dependencies and so on might force us sometimes to use that. So, it has been adopted since a while. But, I was curious to get your impression on the fact that the ODBC 64 bits does not support DBase IV. Would you have any information that this will never be the case or might be in the near future?
