Daenth:
I've seen many script use return [something]; in their script. Destiny told me that it returns information but did not go into details. So, I'm wondering what it does.

Kalphiter:
echo(returnasdfasoidfjao());

function returnasdfasoidfjao()
{
return "returnasdfasoidfjao";
}

Err, worded my post wrong.
What does it do?

Red_Guy:
example:

function go()
{
%var = myFunction(8);
echo("var = " @ %var);
}

function myFunction(%stuff)
{
%value = %stuff + 2;
return %value;
(or just: return %stuff + 2; )
}

then in the console you say:
go();
and get back:
var = 10

-or

echo(myFunction(2));
and get back:
4

Huh, but where would you use this?
