> Is there a way to change the case of a bit of a string?

Difficult to give definite answer. As you post from .co.uk
the standard answer would be

translate($x,'abcdefghijklmnopqrstuvwxyz',
             'ABCDEFGHIJKLMNOPQRSTUVWXYZ')

But this can get tedious if you are using a language that
uses accented letters or sz or ... In that case it might be
better to use an extension function to call out to some
more locale-aware string  handling library.
