Right. Algebraically, it isn't practical to solve this for SN. That probably means you're going to need a iterative solution. That is, you start with a guess, see how far off you are, and refine the guess until you narrow in on a solution. That means you'll have to figure out whether raising SN gets you closer or farther away from a solution. -- Tim Roberts, t...@probo.com Providenza & Boekelheide, Inc. -- http://mail.python.org/mailman/listinfo/python-list
