And that looks a bit simpler than a bitslice, I'll see what I can cobble up when I'm awake again. Its been one of those days. I turned off the AC and opened the garage door, but up around 90F all day has worn me out. Getting old isn't the fun the insurance pedlars talk about. :( Thanks Sebastian. -- Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
