An example of the coding style of CLISP, the Algol-like infix notation of Interlisp. The program, a text formatter, is the sample code of Larry Masinter's thesis which described a program analysis tool evolved from of Masterscope.

@interlisp.orgOn Medley Interlisp press Ctrl-B (B as in break) to interrupt a computation and bring up the debugger (break window). Here we did it while running an infinite loop that prints the loop index.
@interlisp.orgInterlisp source files contain a file map, a data structure with the locations of functions & definitions within the file. This metadata is a hint to the system for directly loading or accessing the definitions, with scanning the file as a fallback.
@interlisp.orgThis video demonstrates some basic features of SEdit, one of the structural editors of Medley Interlisp: selecting, copying, deleting, and moving Lisp expressions.
@interlisp.orgSection "Medley as an Interactive Environment" of the Interlisp manual is an executive summary of the Medley programming environment and its main facilites.
"[...] a completely self-sufficient environment for developing and using Medley programs."
@interlisp.orgOn Medley Interlisp the Snap item of the background or window title right-click menu lets you capture a screenshot of a portion of the screen you are prompted to swipe out. Here is the background menu with a captured copy of the Medley logo window.
@interlisp.orgThis blog post outlines the history of the advice facility in Lisp and its early implementations in BBN Lisp and its successor Interlisp.
@interlisp.orgMATCH is an Interlisp library module for pattern matching, binding, and replacement of Lisp expressions. Other Interlisp tools support this pattern matcher such as the TTY structure editor.
@interlisp.orgCOBOL in the Interlisp environment? Along with Fortran and a "Bitmap Editor as good as MacPaint" it was in a wishlist of system improvements and new features the Interlisp group compiled in the late 1980s.
@interlisp.orgWe honor some of the key contributors to Interlisp who are no longer with us: Warren Teitelman, Danny Bobrow, John Sybalsky, and Steve Purcell.
@interlisp.orgMargot created this art with the Interlisp bitmap editor (left window) and experimented with layering it over itself using the BITBLT graphics operation (right window).
@interlisp.orgIn the Interlisp environment the Process Status Window (PSW) is a tool for monitoring, manipulating, and debugging processes . An Interlisp "process" is what we now call a thread.
