Sounds as if my testing was imcomplete.
I had tried it in the command window by

setting buffering to 3,
issuing an APPEND BLANK
changing the field
doing GOTO RECNO()

and it worked. Based on what you said, I don't doubt that it won't in different circumstances.

The bigger problem, which I didn't notice (and should have tested) before I posted, is that after all this, the changes had been posted and TABLEREVERT() was no longer available. Since that was the reason for the original post, it looks as if I was wrong on several counts.

Thanks for the lesson...........Rich
