If you ever need to change them, then whoever created the base class either didn't think things through properly, or you're not. Imagine a class that sets the value of π (as is the erstwhile example for constants) If further classes that implemented it were of a particular historical persuasion, then they might want to redefine the constant as just 3. It seemed like a good idea to the historical Roman Catholics at the time (it was defined as 3 in the Bible after all) but it doesn't make it the correct value (imagine the problems with volume calculations!) > > Constants are so called for a good reason! And in the class that I want to enforce the presence of the constant, it will be constant. I just want to enforce the presence. -- ----- Richard Quadling "Standing on the shoulders of some very clever giants!"
