OpenDialog

OpenDialog is a software application developed by IBM for the OS/2 operating system. It was designed to provide a graphical user interface (GUI) for the operating system, allowing users to interact with the system through windows, icons, and menus. The application was part of the Presentation Manager, IBM's GUI framework for OS/2.

OpenDialog was first released in 1988 and was an integral part of the OS/2 environment. It allowed users to manage files, run applications, and perform various system tasks through a user-friendly interface. The application supported multiple windows, drag-and-drop functionality, and other features that were considered advanced for its time.

Despite its capabilities, OpenDialog faced competition from other GUI-based operating systems, such as Microsoft Windows and Apple's Macintosh. Additionally, the rise of graphical user interfaces on other platforms, including Unix and Linux, posed a challenge to OS/2's market share. As a result, IBM eventually discontinued support for OS/2 and OpenDialog in 2006.

OpenDialog's legacy lives on in the form of the IBM Workplace Shell, a modern desktop environment for IBM i, which provides similar functionality to OpenDialog. The Workplace Shell is designed to be compatible with IBM's midrange systems and offers a range of features for managing files, running applications, and performing system tasks.
