The table involved is never closed until the operation is complete. If a table remains open, I read somewhere that Fox only actually writes to disk at certain intervals (something like once every five minutes). I have been interrupting the program after a few hundred records. I may have interrupted the operation before an actual physical write to disk, thereby getting the memo from the previous overwrite. In a Belt and Suspenders move, I also added a FLUSH every 1000 records.

FLUSH should reduce data corruption, unless your disk has write-cache enabled. On the other hand, FLUSH after every record would make your program very slow - so once every so many records seems like a decent compromise.
