An informal name for the text editor which came with later versions of
MSDOS - officially it is called 'The
MS-DOS Editor', but everybody in the entire world calls it 'edit' or 'DOS edit'. It uses the same environment as
QBASIC and requires the presence of qbasic.com to run; the blue screen and ASCII border is familiar to millions of PC users from the early 1990s until 1998-ish, by which time Windows had finally removed the need to fiddle about with config.sys and autoexec.bat files (for most users (most of the time)). If you used
POVray or were a programmer, Edit was your friend.
Although version 1.0 has a copyright date of 1987; I believe that this is retrospective, and that it was first included with DOS V5.0 as late as 1991 - before which EDLIN was the standard DOS editor. It will work with versions of DOS back to 2.0.
Edit is, IMHO, superior to Windows Notepad - the interface is friendlier (the default text colours are a soothing light grey on dark blue, and the look'n'feel were similar to Borland's 'Turbo' range of programming languages), and it has marginally more '3l33t' status, if anything running under DOS these days could be said to possess cool.
