I've managed to track down the problem.  Because I was automating some of
the testing around this I hadn't left a long enough delay before
displaying the directory.  It turns out that it takes a little longer
than I expected for the SAVE command to complete the write.  Once I left
a bigger delay before checking the directory everything was fine.  It
also appears that there is no need to call CLOSE either.


Best wishes
