As I said in the part of my reply that you clipped, it "works" in that
it returns the same value as the previous solution based on 'name
extension'.  In your example, both solutions treat 'document.ps' as
the base name and '.gz' as the extension.  That may or may not be
correct for your application; the text item-based solution is flexible
enough that you can change it to suit your needs.
