PL/I

PL/I (Programming Language One, pronounced /piː ɛl wʌn/ and sometimes written PL/1) is a procedural, imperative computer programming language initially developed by IBM. It is designed for scientific, engineering, business and system programming. It has been in continuous use by academic, commercial and industrial organizations since it was introduced in…
