Never mind. It sees EOF again.
Nothing that restarting OS X couldn't cure, it seems.
(I had cycled Filemaker, Entourage, Script Editor, and Script Debugger
several times without success).

orders.txt is a raw ASCII file containing records, which contain

The fields are delimited with fs (ASCII 28), and the records are

ASCII characters, including newlines. There are no non-ASCII (>127)
bytes in the file.

f = ASCII 28, r = ASCII 30. Digits represent ASCII data.
I was successfully reading these records up until very recently! I've
done nothing to change the format of the ASCII file, nor do I *think*
I've touched anything in the Applescript that's involved with reading
each record from the file into an Applescript list.
Now, it reads okay up through the final record. On the next read,
instead of entering the 'on error' block indicating it's hit EOF, it
continues to return a portion of the final record!! And I'm using the
"right" delimiter characters for fs and rs now. Any ideas what
happened, or at least how to read dependably?
Thanks, Chap
