I've got most of it.
But one thing not sure...
2>nul (no redirection?) the nul device?
Why is it needed after RD?

Yes, , that's why I was saying in previous posts that I might be figuring it out once I'd use it when I code on my own. Anyway, thanks.

Oh... yes, I see. It makes sense to me now. Thanks for all that a lot.

Half clear. Maybe next time when I come across a practical use of it, I may understand it better than just read people's explanation. Anyway, thanks for the explanation given.

Well, how about this?



Is it what you said I set an errorlevel for this batch program?

Yes, I started another cmd.exe and it worked.
But what's the use of specifying a number for the command EXIT?

exitcode Sets the %ERRORLEVEL% to a numeric number.
If quitting CMD.EXE, set the process exit code no.

Could ya explain a bit for the use of this?

Well, what I don't understand is
In your example,
Are we using the default setting of ERRORLEVEL of the command EXIT?
Or
setting the ERRORLEVEL for EXIT?

And I tried your example in CMD
When I typed

It exits.

And in your example,
Are you setting the ERRORLEVEL (1,2) for EXIT?

But does the command

set the errorlevel or it uses the errorlevel?

Could I ask a bit about the use of ERRORLEVEL in DOS?
In the EXIT case,

Safely setting the ERRORLEVEL to 1. What does it mean?
