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:
“Perhaps you can tell me why in this country nobody ever does anything. Nobody ever writes any music or starts any revolutions or falls in love. All anybody ever does is to get drunk and tell smutty stories.”
—John Dos Passos (1896–1970)
