Doug,

>In 17 years of working with xBase languages, I've never had a problem with PACK, nor have I ever heard of anyone actually having a problem. I suspect this is one of those theoretical issues.

Well, I'm curious now. Does PACK reclaim any space originally occupied by the table as it is working, or does it need free space as large as the non-deleted records? I had assumed that you might have a problem if disk space was tight, and not just if the process was interrupted by a system crash or power outage.
