What is PL/I?

PL/I (Programming Language One) is a procedural, imperative computer programming language developed by IBM in the 1960s. It was designed to combine the best aspects of ALGOL, COBOL, and FORTRAN, aiming to be a versatile language suitable for both scientific and business applications. PL/I features include extensive data types, powerful string handling, recursion, and exception handling. While less widely used today than in its prime, PL/I is still used in some legacy systems, particularly in mainframe environments. It allows for a wide range of programming styles, and has features to handle tasks ranging from commercial to system programming.
