I wanted to get stuff done, not learn a new editor, so that was fine.

An infamously {losing} text editor. Once, back in the 1960s, when a text editor was needed for the PDP-6, a hacker crufted together a {quick-and-dirty} `stopgap editor' to be used until a better one was written. Unfortunately, the old one was never really discarded when new ones (in particular, {TECO}) came along. SOS is a descendant (`Son of Stopgap') of that editor, and many PDP-10 users gained the dubious pleasure of its acquaintance. Since then other programs similar in style to SOS have been written, notably the early font editor BILOS /bye'lohs/, the Brother-In-Law Of Stopgap (the alternate expansion `Bastard Issue, Loins of Stopgap' has been proposed). 2. /sos/ n.
