Software used to create and edit files that contain only text; for example, batch files, address lists and source language programs. Text editors produce raw ASCII or EBCDIC text files, and unlike word processors, do not usually provide word wrap or formatting (underline, boldface, fonts, etc.).

Editors designed for writing source code may provide automatic indention and multiple windows into the same file. They may also display the reserved words of a particular programming language in boldface or in a different font, but they do not embed format codes in the file. See source code editor, hex editor and DOS Editor.
