Further thought: How do you folks arrive at those logic diagrams shown at several locations in the Integrators Manual I just printed fresh last Thursday? It seems to me that graphing utility could be useful in spotting what I so nicely screwed up. :) Cheers & Thanks, Gene -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
