My bad Rob, I should have searched myself. Only excuse was that I had a hell of a bad day yesterday, having to junk 2000 lines of SAS code I wrote last week, and my brain wasn't functioning properly. Add in that the ambient temperature here yesterday was 45C with the humidity factored in...
Anyway, thanks for the link.
