Yes, kbman covers only one of the two implementations that
cohabited the PDP-11. The other was the same language, with
software paging, so it could have a larger data space.

Various aspects of the language were borrowed from PL/I,
BCPL and Algol 68. ++ and -- were novel operators. The
reversal of Algol's assignment operators (e.g. -=
became =-) was eventually repealed in C.
