An Interactive text editor has become an important part of almost any computing environment.

Text editor acts as a primary interface to the computer for all type of “knowledge workers” as they compose, organize, study, and manipulate computer-based information.

An interactive debugging system provides programmers with facilities that aid in testing and debugging of programs.

Many such systems are available during these days. Our discussion is broad in scope, giving the overview of interactive debugging systems – not specific to any particular existing system.

Text Editors Overview

An interactive editor is a computer program that allows a user to create and revise a target document.

Document includes objects such as computer diagrams, text, equations tables, diagrams, line art, and photographs.

Here we restrict to text editors, where character strings are the primary elements of the target text. Document-editing process in an interactive user-computer dialogue has four tasks

• Select the part of the target document to be viewed and manipulated

  • Determine how to format this view on-line and how to display it

  • Specify and execute operations that modify the target document

• Update the view appropriately
