[Discuss] learn or teach programs

[gaf at blu.org (Jerry Feldman)]

I used learn on our Unix (version 7) system back in 1979 or 1980. At
that time we were using Unix on a PDP-11. We were implementing a
Microsoft Xenix on one of our products, and I wanted to lean C
programming. I have a very ancient K&R I used to learn C.
