WLanguage is a programming language for Windows-based applications. It is used with the WinDev, WebDev, and WinDev Mobile integrated development environments (IDEs) designed by the French company PC SOFT. WLanguage simplifies coding by providing extensive libraries and pre-written functions that handle platform-specific tasks, such as graphical interfaces for creating responsive designs and forms without deep knowledge of GUI programming. The language supports object-oriented programming paradigms with inheritance and polymorphism while including features like automatic memory management through garbage collection. Developers can use WLanguage to create enterprise-level applications on Windows, Linux, or macOS servers thanks to its cross-platform capabilities provided by the AWP (Application Web PC SOFT) engine in combination with WebDev technology.
