Jinx, Gaston: I wrote each of you detailed responses, but deleted them because I became convinced that you will never 'get it' until you find yourself on the receiving end (= maybe, never). As long as a set of rules suits you, you will find ways to rationalize them and even joke about "eliminating the 0.1%". It was worth a try. At least now I can see how things are more clearly. Sorry for wasting everyone's time. Vitaliy -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
