Short for Programming Language for Business, PL/B is an English-like high-level programming language that offers screen, file and character string manipulation. The PL/B source code will compile and run without changes across multiple platforms and it incorporates strong file access capabilities that distinguish it from other languages. PL/B is also multi-user friendly, as no additional code is required for files to be shared among many users. PL/B was formerly called DATABUS and designed by Datapoint in the early 1970s. It was originally considered an alternative to COBOL.
