I was on the internet, learning(TRYING to learn) about variables, but I still don't really get it. One of the examples were:
Code: [Select]COPY MYFILE.TXT [highlight]%userprofile%[/highlight]\DesktopWhat would that do? Especially the highlighted part.That would copy the file onto the username's desktop.

Variables are objects whose values can change. Very useful in BATCH and programming.Some environment variable like userprofile are preset by the operating system. To get a list of current environment variables and there values OPEN a command prompt and type:

C:>set

You will get a list of all variables.
You can set a variable like this:

C:>set MYVAR=hello user

you can then use the variable like this:

C:>echo %myvar%

which will display on the screen:

hello user

Hope this GETS you started. For more info about the set command and the cool STUFF you can do with it type:

C:>set /?

Or just look up the command reference in the internet here:
