But where exactly is :eof going to?
That's exactly what I was wondering but I decided not to ask it.

It's a default standard for batch scripters to use, habit for me when I pipe arguments to calling blocks in batch, as I may want to call it but never actually go to the code, and exit when i'm done with the main bit before unnecessarily going to those calls.

So it actually go to a code block that doesn't exist and quits?

:nono: No... It's a command which became available in Windows versions of NT 4 and above which indicates the end of a function or subroutine and returns the calling code to the label of that function.
Example:
Code:
@echo off
call :setvar 10
echo Stored Variable...
goto test
:setvar
set /a num=(%1) + 1
goto :eof
:test
echo This is your new var... %num%

Okay thanks, I understand it now

As well as I do I never knew that

"Functions" in batch are very useful if you know how to send the arguments to a label with CALL
