My comments earlier were about CP/M's Ed. I've not used Ed on an ICL but presumably it's the same as the usual UNIX version. What's the problem getting people to understand the commands? Is it that these days everyone is bought up on GUI pull-downs and that no one's prepared to take the time to learn them? Or perhaps part of it is that what I mentioned, there's too many different editors around and most will prefer ones without seemingly difficult/cryptic commands? To me, learning commands/keyboard shortcuts is always preferable to just menu operation.
