Abstract

This paper presents a new system for Lisp object inspecting. The author has implemented a system called "List Window" which provides Lisp programmers with a method for inspecting S-expressions on a screen. This system was designed in order to help Lisp programming, especially debugging.When developing the List Window system, it was necessary to output, a big list into a given sized terminal with proper indentations. The system sets a focal point in a list and truncates elements which are far from the focus. Main parts of this paper describe this method of truncating branches of a list.
