RPG (Report Program Generator) is a high-level programming language developed by IBM in the late 1950s primarily for business applications. Initially designed to streamline the process of generating reports, RPG has evolved to handle a wide array of functions beyond reporting, such as file input/output, data manipulation, and calculations. It is widely used on IBM's midrange computers like AS/400 and System i due to its effectiveness in managing large amounts of data efficiently and its user-friendly approach that appeals to non-programmers.
One key feature distinguishing RPG from other programming languages is its historical focus on report generation with specialized syntax for creating detailed reports. Its integration capabilities with IBM midrange systems like AS/400 and System i enable seamless interaction and data handling within those environments. The language's efficiency at processing large volumes of data on server-side operations makes it a preferred choice for businesses utilizing IBM platforms. This user-friendly structure allows non-programmers to navigate the language easily for various application development tasks involving file input/output, data manipulation, calculations, and report creation.
RPG competes with languages such as COBOL, Java, Python, and C#, which offer robust capabilities for developing business applications with diverse functionalities. While COBOL remains significant in legacy systems management, Java, Python, and C# are popular for their versatility and cross-platform compatibility. Despite this competition, RPG's specialization in report generation and its smooth integration with IBM systems provide significant advantages for businesses requiring precise reporting functionalities. Its efficiency in handling server-side operations further distinguishes it as an effective tool for data-intensive business processes on IBM platforms.
