MS-DOS Eitor is a text editor that comes with MS-DOS (since version 5) and 32-bit versions of Microsoft Windows. Originally (up to MS-DOS 6.22) it was just a short stub that started QBasic in editor mode. Since DOS 7 (Windows 95), QBasic was removed and the MS-DOS Editor became a standalone program. Although it kept the COM file extension for compatibility, it is actually an EXE.
