   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
