I now suspect a tyro opened an earlier version of the file in TPU and
rewrote it on EXIT (when a QUIT was intended) and TPU did the changes.

to create the version in question.

Thanks for the vote of confidence. Yes I fixed it with
SET FILE/ATTR=(MRS=0,LRL=32767) TEST.LOG
once I determined the contents was correct.
