Ah.. thanks guys,

Yes, that old 'functional' bit of code I require is long overdue for a re-write - if only I can find the time (sigh)

And I'm so sorry to have troubled you on such a trivial thing re open().. Since its a new setup I didnt have the correct folder to write into.

I mis-interpreted the warning thinking it was saying I had my lines of code the wrong way round :-) (which logically they were if the file was not opened in the first place)

Keep up the good work!
