So, you are not "small" at all. Why that requirement then? It seems very 
pointless. Essentially, all you need is to get it to run under RT-11 
with TECO, and it will run on any PDP-11. The only difference will be 
speed. And since you're running under simh, you can run as fast as you 
want (well, almost anyway), or as slow. What point is there to request 
the information about which PDP-11 actually was the slowest?

Won't make a difference either, as your TECO program will be identical. 
And so can your RT-11 be.

You don't do it like that. You create the command in the main buffer, 
with all the glory you want. You then store it in a q-register, and then 
you execute it.

Getting file information pretty much is a no-do in TECO, yes. Deleting a 
file... Hmm, I don't think there is a command for that either.
EG is not really a good substitute, since it will mean you leave the 
TECO environment.

Definitely not a problem.

Cookies should not be a problem either.
