an OS
Not only in DOS but in any OS user communicate with OS by shell.
MS DOS
If you are talking of DOS OS, no it is not possible as DOS is a single user, single tasking OS but if you are talking of Windows then yes you can open multiple DOS windows and do different work.. But please remember that this is the properties of Windows, not DOS..
DOS is an OS and Visual Basic is an Application Software..
There is no DOS mode to get in to in Mac OS X and so there is nothing to get out of.
Mac OS came first, as it was introduced by Apple in 1984. Linux followed, with its first version released in 1991 by Linus Torvalds. DOS, specifically MS-DOS, was released by Microsoft in 1981, making it the second of the three to debut, but after Mac OS. Thus, the chronological order is Mac OS, MS-DOS, and then Linux.
