Hi All
Thanks for that everyone, especially Mark. That was just what I needed
to be able to do the job. It does work.
Articles and programs in Beebug Vol.8 No.8 and No.9, Vol.9 No.3 and
No.9 have helped me to understand how this is now done. Now I have to
break the news to Barrie that he needs to alter his software so it works
in the RFS......
