Editing MS-DOS Editor (section)

=== Original ===

The Editor version 1.0 appeared in [[MS-DOS]] 5.00, [[IBM PC DOS]] 5.0, [[OS/2]], and [[Windows NT 4.0]]. This version relies on [[QBasic]] 1.0. Hence, it uses a [[text-based user interface]] (TUI), and its color scheme can be adjusted. It can only open one file, but can open the quick help file in a split window.

The Editor version 1.1 appeared in MS-DOS 6.0. It uses QBasic 1.1 but no new features were added to the Editor.

IBM PC DOS 6 dropped the Editor in favor of another text editor called [[E (PC DOS)|E]], which supports mouse and menus in version 7.0.

The Editor version 2.0 appeared with Windows 95, as standalone app that no longer requires QBasic. It has a [[multiple-document interface]] and can open up to 9 files. The screen can be split vertically into two panes which can be used to view two files simultaneously or different parts of the same file.  It can also open files in ''[[Binary file|binary]] mode'', where a fixed number of characters are displayed per line, with [[newline]]s treated like any other character.  This mode shows characters as [[hexadecimal]] characters (0-9 and A-F).  Editor converts [[Unix]] [[newline#Representation|newlines]] (LF) to DOS newlines (CRLF) and has [[computer mouse|mouse]] support. This version has been included with all 32-bit x86 versions. Being a 16-bit DOS app, it cannot run on [[x64]], [[IA-64]], or [[ARM64]] versions of Windows.

The Editor may be used as a substitute for [[Windows Notepad]], although the 16-bit version is limited to files smaller than {{nowrap|300 [[kilobyte|kB]],}} depending on how much [[conventional memory]] is free.<ref>{{cite web|url=http://support.microsoft.com/kb/63713|title=Largest Document Size MS-DOS Editor Can Edit|date=2003-05-12|archive-url=https://web.archive.org/web/20121022014157/http://support.microsoft.com/kb/63713|archive-date=2012-10-22|access-date=2008-06-12}}</ref>
