   Thanks for the suggestion.  I gave it a go but unfortunately it still   
   gives the same result.

   Sadly not.  However, I'm not sure that a CLOSE is necessary as I noticed   
   in other code examples that it isn't used.  I've tried without it and   
   also checked for errors via a carry after the SAVE but still no joy. If   
   you or anyone else has any ideas I'd love to get this working.   
      
      
   Best wishes
