Yes now that you mention it, that is a _much_ better way. ...snip > This concept of using incremental controls is a fundamental principle > adopted by NIST when they were designing EMC.

(I remember seeing on TV a mountain lion chasing a rabbit. It seemed like the lion could have taken the rabbit down at any time, but was entertained with the chase, or something. When he decided he had had enough, he just extended his paw and tapped the rabbits hind leg at just the right time and made the kill. If I had not been lazy, I could have researched my question and found the answer, but then no one would have read this story.) > Regards, > > John Kasunich -- Kirk Wallace (California, USA http://www.wallacecompany.com/machine_shop/ Hardinge HNC lathe, Bridgeport mill conversion, doing XY now, Zubal lathe conversion pending) ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
