I don't think we need to dive into the pros and cons of different 
language or environments.

Suffice to say that I wrote a fairly feature rich Emacs clone in TECO-8. 
TPU would not even get close to running on a PDP-8...

Not a direct argument for TECO on VMS, but it might say a little about 
how complicated or easy it is to write a screen oriented editor in TECO.
