CMUD

CMUD, often referred to as Carnegie Mellon University Database, is a software system developed at Carnegie Mellon University. It is primarily known as a text-based user interface toolkit designed to facilitate the creation of console applications. CMUD allows developers to build interactive command-line programs with features typically found in graphical user interfaces, such as menus, windows, and forms, all within a text-based environment.

The toolkit provides a set of functions and structures that enable programmers to manage screen display, capture user input, and define the layout of text-based interfaces. This makes it possible to develop more sophisticated and user-friendly command-line applications than would be achievable with basic input/output operations. CMUD was particularly influential in the development of MUDs (Multi-User Dungeons) and other text-based online games, where its capabilities were extensively utilized to create rich interactive experiences. While modern computing often favors graphical interfaces, CMUD remains a notable example of advanced text-mode application development.
