How to use & w/ a function parameter

[wey97]

In C++, you can pass a parameter to a function using &
so that the parameter you pass it is actually modified
and you do not have to return that parameter.
Like this:

void Function(int &x){
x = 100;
}

Then if you say:

int a;
Function(a);

Then a is actually 100 now.

Well, how do you do this in VB?
