The paper says they were working on a specification for C. It also says the size of 85% of the compiled editor code is ~55K bytes, a long way from 2M bytes. As an aside, when trying to write a specification for the Bourne Shell, Theo discovered all those wonderful loopholes like <<`echo "Goodbye World"` which cause hours of endless amusement at conference exhibitions. (One machine we tried it on had to be restored from floppies). Jim McKie Centrum voor Wiskunde en Informatica, Amsterdam mcvax!jim
