I would change Carbon's code slightly. You don't really need the /i because we are only comparing numbers. I would also add brackets (or quotes) to the comparisons, otherwise, if the user just presses [Enter] the variable would be blank and the batch file would probably exit with an error.
if {%input%}=={1} goto :wee
Also, I don't think QUIT is not an internal command or standard external command. I would probably change that to
goto :EOF
