Hi all.

I am self taught... So please bear with me.

1)
When writing a function, what is best way to know if I should cast :Void? For example:

function gotourl():Void { getURL(META); };

1.5)
In actionscript, is this considered casting? Or, "assigning a datatype"? Please clarify.

1.75)
When would I not use :Void? Examples of other types of function/methods that use something other than :Void?

2)
Lets say I have a video object on the stage... It has an instance name of "myVideo"... Via actionscript, I want to assign the instance name to another variable. What kind of datatype would that be?

--<snip>--
var theVid:Object = myVideo; // Not tested.
...
theVid.play("foo.flv");
--</snip>--

Or:

--<snip>--
var theVid:String = "myVideo"; // Not tested.
...
theVid.play("foo.flv");
--</snip>--

Is there a good technique for determining what type of datatype something is?

Hopefully those are not too noob of questions for all you pros. :)

Have a great day/night!
Cheers,
Micky
