Here it is straight from the help files:
function
Syntax
function functionname ([argument0, argument1,...argumentN]){
statement(s)
}
function ([argument0, argument1,...argumentN]){
statement(s)
}
Arguments
Hope this helps...
functionname The name of the new function.
argument Zero or more strings, numbers, or objects to pass the function.
statements Zero or more ActionScript statements you have defined for the body of the function.
Description
Action; a set of statements that you define to perform a certain task. You can declare, or define, a function in one location and call, or invoke, it from different scripts in a movie. When you define a function, you can also specify arguments for the function. Arguments are placeholders for values on which the function will operate. You can pass a function different arguments, also called parameters, each time you call it.
Use the return action in a functions statement(s) to cause a function to return, or generate, a value.
Usage 1: Declares a function with the specified functionname, arguments, and statement(s). When a function is called, the function declaration is invoked. Forward referencing is permitted; within the same Action list, a function may be declared after it is called. A function declaration replaces any prior declaration of the same function. You can use this syntax wherever a statement is permitted.
Usage 2: Creates an anonymous function and returns it. This syntax is used in expressions, and is particularly useful for installing methods in objects.

Example
(Usage 1) The following example defines the function sqr, which accepts one argument, and returns the square(x*x) of the argument. Note that if the function is declared and used in the same script, the function declaration may appear after using the function.
y=sqr(3);
function sqr(x) {
return x*x;
}
(Usage 2) The following function defines a Circle object:
function Circle(radius) {
this.radius = radius;
}
The following statement defines an anonymous function that calculates the area of a circle and attaches it to the object Circle as a method:
Circle.prototype.area = function () {return Math.PI * this.radius * this.radius}
