Hi Jim,
Tom did answer actually! (Although it was first thing in the morning
and he hadn't had any caffeine so he may have forgot to copy the list in
;) )
I forget what he said the format was now, and I haven't got his e-mail,
but I've just done a regex to match one or more characters before and
after the "/", which works.
Andy.
