Are you using Lisp applications of Medley Interlisp or doing coding projects? We would love to hear what you are doing with the system.

Modern Medley Interlisp can read and write files where 16 bit character codes are represented as UTF-8 byte sequences or UTF-16 byte-pairs, and convert from and to Unicode codes to equivalent internal Medley codes. For details see:

The SEdit structure editor of Medley Interlisp lets you also modify arbitrary list structures and data, not just Lisp code. In this example the ED function calls SEdit and returns the modified object.

Hello from the Medley Interlisp Project! We revive and modernize the Medley Interlisp extensible graphical operating and programming environment created at Xerox PARC.
We post news & updates, tips, historical info, and more. We look forward to connecting with researchers, software preservation experts, Lisp programmers, retrocomputing enthusiasts, and anyone interested.
