DOS Plus (erroneously also known as DOS+) is an operating system written by Digital Research, first released in 1985. It can be seen as an intermediate step between CP/M-86 and DR-DOS.
It is able to run programs written for either CP/M-86 or MS-DOS 2.11, and can read and write the floppy formats used by both these systems. Up to four CP/M-86 programs can be multitasked, but only one DOS program can be run at a time.

Famous quotes containing the word dos:
“If I were sufficiently romantic I suppose I’d have killed myself long ago just to make people talk about me. I haven’t even got the conviction to make a successful drunkard.”
—John Dos Passos (1896–1970)
