B
(language)A systems language written by Ken Thompson in
1970 mostly for his own use under Unix on the PDP-11. B
was later improved by Kerninghan(?) and Ritchie to produce
C. B was used as the systems language on Honeywell's
GCOS-3.
B was, according to Ken, greatly influenced by BCPL, but the name B had nothing to do with BCPL. B was in fact a revision of an earlier language, bon, named after Ken Thompson's wife, Bonnie.
