All DOS   -   All Day   -   Alright!!!

"DOS" stands for Disc Operating System. It is fully
command-line oriented; that is, one may run the system
exclusively via key commands with no pointer device.

    Although graphic desktops are available, one is never forced to use any because every operation may be accomplished right at the command line without necessarily moving to other drives or directories should one so choose.

    The latest versions of DOS are very powerful and can be asked to do or automate just about any computer task. If you want to free yourself from the drudgery of desk-rodent point & clicking, huge bloatware programs like Windoze which consume more resources than are available in your home town, and wish to be relieved of the general nuisance and tedium of Graphic User Interfaces, upgrade to DOS!

The Command Line is King!
