It is one of the oldest and most respected business programming languages still being used today.&nbsp;<\/p>\n\n\n\n<p>IBM originally introduced RPG in 1959 for the IBM 1401 computer system, and surprisingly, many large organizations still rely on it for mission-critical operations.<\/p>\n\n\n\n<p>Banks, insurance companies, government agencies, retailers \u2014 they&#8217;re all quietly running RPG in the background, processing billions of dollars worth of transactions every single day. Most people have no idea. And honestly, that&#8217;s kind of the point. It just works.<\/p>\n\n\n\n<p>This guide breaks down everything you need to know about the RPG programming language \u2014 what it is, where it came from, how it works, and how you can start learning it. Whether you&#8217;re a complete beginner, an IT student, or someone stepping into IBM i development for the first time, you&#8217;re in the right place.<\/p>\n\n\n\n<div id=\"ez-toc-container\"

It was built from the ground up to handle business tasks \u2014 things like reading data from files, processing records, and generating reports. Pretty straightforward stuff, but incredibly important for how businesses actually operate.<\/p>\n\n\n\n<p>It runs on IBM i, which you might also know as AS\/400 or iSeries \u2014 IBM&#8217;s family of midrange business servers. These machines are known for being rock-solid reliable, and RPG is basically the native language of that environment.<\/p>\n\n\n\n<p>A few things that make RPG stand out \u2014 it&#8217;s compiled, meaning your code gets converted into machine-level instructions before it runs, which makes it fast. It&#8217;s also strongly typed, so you define your data precisely. And it has something called fixed-cycle processing, where the program automatically loops through records without you having to write all that logic manually.<\/p>\n\n\n\n<p>That last part is honestly what made RPG so popular with businesses back in the day. Less code, fewer mistakes, faster results.<\/p>\n\n\n\n<p>And today? It&#8217;s still relevant because replacing decades of working RPG code would cost companies millions. So instead, they keep it \u2014 and keep hiring people who know it.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"History_of_RPG_Programming_Language\"><\/span><strong>History of RPG Programming Language<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>The history of RPG programming language goes all the way back to 1959, when IBM created it for the IBM 1401 system. The original goal was simple \u2014 replace punch card machines with something programmable. Not exactly glamorous, but it worked.<\/p>\n\n\n\n<p>From there, the language kept evolving. RPG II came along in the 1960s and added more structure. RPG III brought better data handling in the 1970s. Then RPG\/400 arrived with the AS\/400 system, making it more powerful for business applications. ILE RPG introduced modular programming, and finally RPGLE \u2014 also called RPG Free or Free-Format RPG \u2014 gave developers a much cleaner, modern syntax that actually looks like a real programming language.<\/p>\n\n\n\n<p>Each version basically answered the same question: how do we keep this language useful without throwing everything away?<\/p>\n\n\n\n<p>Quick comparison with COBOL \u2014 both are old, both handle business data well. But RPG is more tightly tied to IBM hardware, while COBOL runs on more platforms. RPG tends to be more concise too.<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-background has-fixed-layout\" style=\"background:linear-gradient(135deg,rgb(255,245,203) 0%,rgb(182,227,212) 100%,rgb(51,167,181) 100%)\"><tbody><tr><td><strong>Note:<\/strong> If you&#8217;re interested in exploring other legacy programming languages, check out our detailed guide on<a href=\"https:\/\/bestassignmentgrade.com\/blog\/simula-programming-language\/\" target=\"_blank\" rel=\"noreferrer noopener\"> <strong>Simula Programming Language<\/strong><\/a> and how it shaped modern object-oriented programming.\u00a0<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"RPG_Programming_Language_Overview_%E2%80%94_Core_Concepts\"><\/span><strong>RPG Programming Language Overview \u2014 Core Concepts<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>If you want to understand how RPG actually works, there are a few core ideas worth knowing:<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Fixed-Format_vs_Free-Format_RPG\"><\/span><strong>Fixed-Format vs Free-Format RPG<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Older RPG used strict column-based coding \u2014 every character had an assigned position<\/li>\n\n\n\n<li>Modern free-format RPG removed those rules, making code cleaner and easier to read<\/li>\n\n\n\n<li>Most developers today prefer free-format, and IBM actively encourages it<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"The_Program_Cycle\"><\/span><strong>The Program Cycle<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>One of RPG&#8217;s most unique features \u2014 a built-in loop that automatically reads and processes records<\/li>\n\n\n\n<li>You don&#8217;t have to write explicit loop logic, RPG handles it for you<\/li>\n\n\n\n<li>This saved developers a lot of time, especially in the early days<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Data_Types_and_File_Handling\"><\/span><strong>Data Types and File Handling<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>RPG supports numeric, character, date, and packed decimal data types<\/li>\n\n\n\n<li>File handling is deeply baked into the language \u2014 reading and writing to databases feels natural<\/li>\n\n\n\n<li>No need for extra libraries or complex setup<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Modules_Service_Programs_and_ILE\"><\/span><strong>Modules, Service Programs, and ILE<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>ILE stands for Integrated Language Environment<\/li>\n\n\n\n<li>It lets you break code into reusable modules and service programs<\/li>\n\n\n\n<li>You can even mix RPG with other languages like CL and C on the same IBM i system<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"RPG_Programming_Language_Examples\"><\/span><strong>RPG Programming Language Examples<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>The best way to actually understand RPG is to see it in action.
