JOG, in case you hadn't noticed, Badour, being incapable of independent thought, is just envious of those of us who aren't. The function that maps terms of a language to objects in the Universe of Discourse has been referenced and described by many. While I haven't before seen "value" defined as just the output of that particular function, it all just falls into place for me, since every value carries with it some sense or meaning and that particular function is integral to the process of attributing meaning to language elements or combinations of language elements.
