Oberon
Another kind of TUI is the primary interface of the Oberon operating system, first released in 1988 and still maintained. Unlike most other text-based user interfaces, Oberon does not use a text-mode console or terminal, but requires a large bit-mapped display, on which text is the primary target for mouse clicks. Analogous to a link in hypertext, a command has the format Module.Procedure parameters ~ and is activated with a mouse middle-click. Text displayed anywhere on the screen can be edited, and if formatted with the required command syntax, can be middle-clicked and executed. Any text file containing suitably-formatted commands can be used as a so-called tool text, thus serving as a user-configurable menu. Even the output of a previous command can be edited and used as a new command. This approach is radically different from both conventional dialogue-oriented console menus or command-line interfaces but bears some similarities to the worksheet interface of the Macintosh Programmer's Workshop.
