RPG II, which stands for Report Program Generator II, is a high-level programming language that was developed by IBM in the late 1960s. It is specifically designed for creating business-oriented applications and generating reports. RPG II is known for its simplicity and ease of use, making it accessible to programmers with limited coding experience.
In RPG II, programs are primarily written using fixed-format statements, where each statement starts in the same column position. The language primarily focuses on data processing and manipulation, with built-in features for file handling, input/output operations, and arithmetic calculations. RPG II also includes extensive support for creating complex report layouts and performing various data formatting tasks.
One of the key features of RPG II is its ability to define records or data structures known as fields. These fields can store various types of data, such as numeric, character, or date values. RPG II provides a range of built-in functions and operators to manipulate and manipulate these fields, enabling programmers to perform calculations, comparisons, and other operations easily.
RPG II programs are typically executed in batch mode, where they process a set of input data and generate reports based on predetermined formats. The language incorporates a top-down programming approach, where a program is divided into separate sections called specifications, each serving a specific purpose within the application.
Overall, RPG II is a versatile programming language that allows users to develop data processing and reporting applications efficiently. It remains widely used in legacy systems and continues to serve as an essential tool in various industries that require robust business applications.
