Keith,

   I overlooked that, thanks.

   Can do. So, scale would equate to width and loc to center, yes? It's been
so many years since I've dealt intimately with statistics and mathematics
that I've gotten quite rusty. (However, I still retain what I need to
accomplish a given objective.)

Much appreciated,

Rich
