A Journey through the History of RPG Programming
In the late 1950s, IBM laid the foundation for a groundbreaking high-level programming language called RPG (Report Program Generator). Originally designed for IBM’s System/3X mainframe computers, streamlining the process of producing customized reports for business customers.
One of RPG’s standout features was its user-friendly approach. By employing English-like statements and a straightforward syntax, even individuals with limited programming knowledge could effortlessly create their tailored reports. Overtime, RPG evolved in supporting interactive applications and data-driven decision-making to cater to the changing needs of businesses.
RPG managed to maintain its prominence as a common language for business applications, especially on the IBM I platform (previously AS/400). It continued to serve as a go-to choice for unique business applications, efficient data access, and seamless report generation.
IBM made significant investments in modernizing RPG to keep up with the ever-changing technology landscape. RPG is relevant in the industry by supporting technologies like web services and integrating a refreshed syntax and grammatical structure. It successfully adapts to the demands of contemporary businesses.
Latest Version – RPG IV Programming Language
Even in the present times, RPG stands tall as a remarkably popular programming language on the IBM i operating system. With RPG IV’s cutting-edge capabilities, AS400 developers can unlock a world of opportunities, propelling their coding prowess to new heights.
In its early stages, RPG’s key strength lay in its innate understanding of the program cycle. Each RPG program executed within a theoretical loop, allowing the same program to apply uniformly to every on-record file. This distinctive concept of matching records was a hallmark of RPG II language.
However, with the introduction of System/38 in 1979, many RPG programmers abandoned the cycle, opting to control program flow differently.
RPG remains a versatile and enduring language in programming. AS400 developers continue to use RPG IV, adapting to modern coding demands while cherishing its rich heritage.
