and p-code in turn was quite explicitly designed as an improvement to Martin
Richards' o-code, which was used (in the late 60s) as the target for
compilation of BCPL, more widely known as the forerunner of C.

Designing an intermediate language that is suitable as a target for multiple
high-level languages and that is also suitable for interpretation on any
physical hardware is a more elusive goal. ICL attempted it with a system
called ALICE in the mid-1970s, but unsuccessfully. It might be easier today
now that 8-bit addressing and IEEE 754 arithmetic have become universal.
