Going back to the beginning, Gil: SQRT(X**TWO+Y**TWO) looks like ~exactly~ the sort of thing that oughta be made a constant rather than being coded more than once. That is, if X, Y and TWO all constants themselves; and if they are not then this isn't an example of what you're talking about. Did you accidentally reverse your meaning? Or what am I missing?

A recent thread here moved me to browse the Ref., where I read that any constant used more than once must be declared and the identifier used instead. Sorta tyrannical enforcement of coding conventions. OK. I agree that 6.62607015e−34 shouldn't be hard-coded more than once. But SQRT( X**TWO + Y**TWO )? Ugh! ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
