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
