Hi All,  
I have a basic doubt…

I have used global declaration like:

var a:String ="";  
var b = 0;  
var c:String = “”;

and I have a written a function called abc

function abc()  
{  
a="";  
b= 0;  
c= “”;  
blah blah blah…!  
}

abc(); //calling this function

I want to know the difference between the first declaration and the second declaration…Is there a difference or is it a re-declaration…?

Plz help…!  
Thanks  
Nirmal.
