PL/I (Programming Language One) is a high-level programming language that was developed in the late 1960s by IBM. It was designed to combine the best features of FORTRAN and COBOL, making it a versatile language for a wide range of applications in the information technology (IT) industry.
Overview
PL/I is known for its extensive functionality and flexibility, allowing programmers to write complex programs with ease. It supports multiple data types, including character, numeric, and boolean, and provides a wide range of built-in functions for mathematical, string manipulation, and logical operations.
One of the key features of PL/I is its ability to handle both scientific and business applications. It combines the mathematical computations of FORTRAN with the file handling and data manipulation capabilities of COBOL. This makes PL/I suitable for a variety of domains, including software development, coding, fintech, healthtech, and more.
