What is The Difference Between RPG And IO, Programming Languages

RPG is a Procedural Programming Language, while IO is an Object-Oriented 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 Object-Oriented Programming Languages

Object-oriented programming (OOP) is a programming paradigm based on the concept of “objects”, which may contain data, in the form of fields, often known as attributes; and code, in the form of procedures, often known as methods. In OOP, computer programs are designed by making them out of objects that interact with one another. (Wikipedia)

While RPG is a Procedural Programming Language, and IO is an Object-Oriented Programming Language

Let us now look at the difference between the two:

What is RPG Programming Language – A brief synopsis

This programming language is used for business applications. It is available with the IBM’s System I midrange computers.

What is IO Programming Language – A brief synopsis

It is a pure object-oriented programming language having a prototype-based object model. It is small in size and can be executed on small portable virtual machines.
