Hello, Sauer, I was thinking about exactly the same thing - if there are perl regexp's than perhaps some of these things could be used. I didn't try \L though, I am no perl programmer, but was very eager to learn if that's possible.
Now seeing that it's not... Well, I will use just another workaround. Actually I only needed to use the lowercase'd variable in a config file and I decided to use Template Toolkit for generating the file.
