I was also considereing using that.  Didn't like to have a duplicate of the 
same, rather large string though.   But that may still be my "640 KB is 
enough for everyone" memories talking though. Programming (small)

I will most likely try it out, if only to see the difference.

:-) I've just ran into the latter, but can't say I've ever used the former.

Thanks.
