Babak,

This is the standard program in windows 2k (maybe in NT but not totally
sure right at the moment) that lets you open a Dos session under windows.
So if you go to the start menu, click on run, type in cmd in the command
line to execute, you will open a dos session under windows.

If you need to operate in Dos with any frequency under windows, you might
want to create a shortcut on your desktop and/or taskbar to click and run
on the fly.

However, there is an other program which also will open a Dos session, BUT
acts somewhat differently - this one is generated by running the command
program under windows.

For example, if you run cmd - when the session opens up, you get:


Microsoft Windows 2000 [Version 5.00.2195]
<C> Copyright 1985-2000 Microsoft Corp.

C:\WINNT>


BUT, if you run command - when the session opens up, you get:


Microsoft<R> Windows DOS
<C>Copyright Microsoft Corp 1990-1999.

C:\WINNT\SYSTEM32>


One of the differences between them involves the mouse - cmd does not give
you a mouse pointer in the Dos session, while command will give you a
square block mouse pointer.

There are differences between them, the biggest one being that command is
more "DOS" like in mature when compared to cmd, more like classic Dos - BUT
I noticed that programs run slower when run in a command session than
running the same programs under a cmd session.

BUT, no matter what, you can NOT get "real" Dos under WinNT based OSs (NT,
2K, XP) since that requires you have to have access to real mode of the
processor, which NT based OSs do NOT allow - for "real" dos and related
type windows programs that need real mode, such as many win95 and 98
programs, you have to still operate in those OSs. WinME, while technically
a 9x based type windows, has enough differences that it lies somewhere
between 9x windows and NT windows. This is the reason that most Dos and
Win9x programs can not run under a WinNT based OS - they need access that
is impossible to obtain.

IF someone needed to have access to both Win9x and WinNT based systems,
since each offers different capabilities and pros/cons, the best solution
has been and remains to have a dual-boot system - install the Win9x based
system and then install the WinNT based system in a DIFFERENT partition
(*** EXTREMELY *** important that they end up in different partitions, or
you have the NT system replacing the 9x system.)

Hope this has not been info overload.

What is the cmd.exe ?
And where can I find a search engine for Windows files
and their descriptions?
