PL/I ("Programming Language One", pronounced /ˌpiːˌɛlˈwʌn/, PEE-EL-WUN) is an imperative computer programming language designed for scientific, engineering, and business applications. It has been used by various academic, commercial and industrial users since it was introduced in the early 1960s, and is still actively used as of 2009.
PL/I's principal domain is data processing; it supports recursion and structured programming. The language syntax is English-like and suited for describing complex data formats, with a wide set of functions available to verify and manipulate them.
PL/I was developed by IBM, at its Hursley Laboratories in the United Kingdom, as part of the development of System/360. Prior to System/360, IBM made several different incompatible models of mainframes for different purposes: some were designed for business use, others for scientific use. The goal of the System/360 project was to develop one series of compatible models to replace all the previous models, and...
