PL/1 programming

PL/I ("Programming Language One", pronounced "pee el one") is a computer programming language designed for scientific, engineering, and business applications. It is undoubtedly one of the most powerful programming languages that has ever been created. It has been used by various academic, commercial and industrial users since it was introduced in the early 1960s, and in fact is still actively used today. See the newsletter[1] ( It is no longer considered a mainstream computer programming language.

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.
