'Why not? TECO is both an editor and a programming language. The first
Emacs was written in TECO.'
Hic Rhodos - Hic Salta!
I have a account on a remote twenex PDP10. There is a editor named emacs. This is a very
archaic piece of software. It doesn't know any teco commands no matter how I tried.
I'm pretty sure that this is teco-emacs. I draw my own conclusions from these
observations which are far away from all these myths.
