There's really no way to give it proper treatment without a whole book's worth of formulae... hence the book references. "Astronomical Algorithms" by Meeus is excellent. BTW, bravo on the BASIC flame! Anyone using BASIC for serious number crunching is probably crippling themself... I'd LOVE to see formulae in algebra in the mags. -Tom R. randolph@est.enet.dec.com
