MS-DOS had edlin, which was their own take on ed. They never made a firm commitment, however, to make edlin the standard editor.

Edlin was the standard editor in dos 3.x. As far as I can remember, edit came later (dos 4.x-5?)

		I don’t remember any tools that output edlin commands that could be piped to it the same way it’s done with ed.
