Interlisp

Interlisp is a programming environment and dialect of the Lisp programming language that was developed in the 1970s, known for its integrated development environment (IDE) and innovative features such as interactive debugging and code analysis. As a pioneering effort in the history of programming languages and software development, Interlisp remains relevant to the tech community today, influencing the design of modern IDEs and programming tools, and continuing to be of interest to developers and researchers studying the evolution of programming environments and Lisp-based technologies.
