This section briefly describes the peculiarities of using Emacs on the MS-DOS “operating system” (also known as “MS-DOG”). Information about peculiarities common to MS-DOS and Microsoft's current operating systems Windows (also known as “Losedows”) is in Microsoft Windows.
If you build Emacs for MS-DOS, the binary will also run on Windows 3.X, Windows NT, Windows 9X/ME, Windows 2000/XP, or OS/2 as a DOS application; all of this chapter applies for all of those systems, if you use an Emacs that was built for MS-DOS.
See Text and Binary, for information about Emacs's special handling of text files under MS-DOS (and Windows).
