Eli: Here is what these are technically as I understand it.
If not true, please correct.

DOS is an independent operating system.

Windows 3.1 (and before) is a graphical user interface dependent upon DOS.

Windows 95 ++ is an independent operating system with added GUI features.
(Windows 95 ++ is NOT a GUI dependent upon DOS.)

Linux is a UNIX-like independent operating system, often packaged with added
GUIs and other things, but not necessarily.

A BASH/EMACS/DGJPP/DOS installation is a simulation of a normal UNIX
operating system. It is dependent upon DOS, but in most aspects gives what
I see when I call up Linux--of course I don't have the nice utilities and GUIs
that normally come with Linux. When I hit bash [Enter] then Emacs [Enter]
I enter a world much like Linux except I am still using DOS and don't have
the many fine features for multi-tasking, and on-line work that Linux has.

There is no intent to praise or disparage any of these systems, my only
purpose is to see if I have it right.

Any comment would be appreciated.

Ralph
