Programming Language for Business or PL/B is a business-oriented programming language originally called DATABUS and designed by Datapoint in 1972[2] as an alternative to COBOL because Datapoint's 8-bit computers could not fit COBOL into their limited memory, and because COBOL did not at the time have facilities to deal with Datapoint's built-in keyboard and screen.
A version of DATABUS became an ANSI standard, and the name PL/B came about when Datapoint chose not to release its trademark on the DATABUS name.[3][4]
