Ed was essentially a stripped-down version of Multics qed. The latter was originally written by Ken. Unfortunately the "Multics Condensed Guide" online at multicians.org describes how strings of addresses were interpreted only by canonical examples for the various editing requests. I have no specific memory of semicolons in qed. I have a vague recollection that semicolons originated in ed, however you should put no trust in this. Maybe Ken remembers. Doug
