Just check %2 and make sure it is blank, like:

if "%~2" NEQ "" (
    echo Too many parms entered.
    exit /b
)

batch script parameters are named %1, %2, %3 ect (up to %9).
So, Just check if %2 hold any value.

But why don't you ignore additional parameters if you arn't interrested in them ?
It is simplier than an akward checking.
