I finally resolved the problem. Still don't know why it happened.

I had to log everyone off the network and reboot the NT server. After that I was able to gain exclusive use of the table and make the changes.

Now to figure out the cause of the bad data......

Thanks very much for all your replies.

Trying to use the table exclusively gives a 'File access denied' message. The table is used on a network, but for my most recent test, I shut down all workstations and ran VFP6 on the server containing the database, with the same result.
