What is The Difference Between PL/I And REXX, Programming Languages

PL/I is a Procedural Programming Language, while REXX is an Interpreted Programming Language

What are Procedural Programming Languages

Procedural (imperative) programming implies specifying the steps that the programs should take to reach to an intended state. A procedure is a group of statements that can be referenced through a procedure call. Procedures help in the reuse of code. Procedural programming makes the programs structured and easily traceable for program flow.

What are Interpreted Programming Languages

An interpreted language is a programming language for which most of its implementations execute instructions directly, without previously compiling a program into machine-language instructions. The interpreter executes the program directly, translating each statement into a sequence of one or more subroutines already compiled into machine code. (Wikipedia)

While PL/I is a Procedural Programming Language, and REXX is an Interpreted Programming Language

Let us now look at the difference between the two:

What is PL/I Programming Language – A brief synopsis

It is an imperative computer programming language targeted at scientific and engineering applications. Mainly intended to perform data processing, it also supports structured programming and recursion.

What is REXX Programming Language – A brief synopsis

Short for Restructured Extended Executor, REXX is an interpreted language developed by IBM. It was designed with an intent to be an easily learnable and readable language. NetRexx is the IBM’s implementation of REXX that offers object-oriented programming. Object REXX is an object-oriented scripting language that is based on REXX.
