PLANC (Programming LAnguage for Nd Computers, pronounced as plank) is a high-level programming language. Compilers were developed by Norsk Data for several architectures, including the Motorola 68000, 88000, Intel x86, and the Norsk Data Nord-10 minicomputers and ND-500 superminicomputer. The language was designed to be cross-platform software. It was mainly used internally at Norsk Data for writing high level systems software such as the upper parts of operating systems and compilers.
