However, lately I've been thinking of writing a modal editor for Linux based on CP/M's ED. I know there is ED and EX on Linux but I prefer ED on CP/M and have been wondering where I could take that idea and possibly replace some of my use of VIM.
MNCPM^Z0TT6Z-3DICP/M^Z
However, there are things I like in ED/EX such as the regular expressions.
Despite my earlier criticism of ED, I've always liked CP/M's command line structure and switch parameters. For example, here's one I think I remember: PIP B:=A: [V O] (I hope that's right, it's been a long time.)
I wonder if that elogence is Kildall's work, as I've never been sure whether GK just took the PDP/DEC command stuff verbatim or whether he altered some items.
