SOS
1.
Scheme Object System.
2. 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).
3. The
PDP-10 instruction to decrease a value.
