Do you mean something like:

function firstfunction()
{
var str = "test";
another(str);
}

function another(x)
{
alert(x);
}

Is it that?

A tiny bit of addition to swons code.
You can get a value returned be a function to,
function firstfunction()
{
var str = "test";
str = another(str);
alert(str)
}

function another(x)
{
alert(x);
return x+" changed";
}

you pass a string to another function mosify it return it back to firstfunction and then use it there

does it work if you set the string as a global variable (outside and before all the functions) then you can call the variable by any function you write afterwards?

var s = new String("firststring");
var t = new String("secondstring");

Ok I get it,you want to know to create a user defined object and then access its local variables.
here take a look at the code snippet below,It creates an object largeView using a constructor that takes 4 parameters.

and then creates an instance of that object and then access its local variables

this.dir=dir;
this.img=img;
this.W=W;
this.H=H;
}
lvObj = new largeView("C:","arrow.gif",400,300);
alert("lvObj.W = "+lvObj.W+", lvObj.H = "+lvObj.H);
</script>
</body>

1 - The HTML 4.01 DOCTYPE doesn't look like that.
2 - In HTML 4.01 the SCRIPT element has no LANGUAGE attribute.
3 - In the naming convention used by JavaScript class names begin with a capitol letter.
4 - It's considered bad programming to access an internal object value directly. You are supposed to use a function.
(Note, these items are in decreasing order of severity.)
