Screenshot of the black and white desktop of a 1980s graphical workstation environment. The desktop has a gray background pattern and some windows with a white background and a title bar with white text on a black background. The main window shows a rich text editor whose buffer contains the output of a function to computer a square root table, and a datestamp returned by evaluating a system function. The Interlisp code of the square root table function is open in another window above the editor.

In a system that is Lisp all the way down like Medley Interlisp you get scripting for free. Pretty much everything has a Lisp API that can be called or inputs data.
Here I inserted in the TEdit rich text editor a table of square roots formatted by a short user function evaluated in the REPL at the top left, and a datestamp returned by evaluating the DATE system function in the small input box (evaled as soon as the right parenthesis is typed, so omitted for clarity).
