I don't see it in V6 distro however. Cheers, -skots -- Scott G.

It appears in the First Edition manual, and according to A Quarter Century of Unix, it's even older than that. "There was also a version of dc, desk calculator, a very very early program. That was actually the first program that ran on the PDP-11. It ran standalone before there was an operating system."
