[RESOLVED] Questions about Variables

1. what is different between:

Code:

---

Set Variable: "bob" = 5

---

and

Code:

---

bob = 5

---

i have read a few things and not much describing how thay are different.
2. Var is like a temporary Variable right? so it deletes itself once it's used right?

no var is not temporary. I have never had a var delete itself or used a set variable.

hi blue you must be thinking about a varibale defined within a function. if you define a variable in a function, that variable is available only within that function and as soon as the function has run it will go back to being undefined.

have a look at this to get a better understanding

Code:

---


hello();

function hello(){

trace("first call: " + greeting);
       
var greeting:String = "hello there";

trace(greeting)// this will output 'hello there'
}

trace(greeting) // this will output undefined

hello(); // this will help u to see that the variable was destroyed as the first call  will now say undefined

---

yeah thats what i ment so thanks.

Personally ive never myself or seen anyone else create a variable using the 'Set' keyword within flash? Does this techinque even exist?

( the only place i use Set w.r.t variables is in my ASP pages)

cosider the following variable

var greeting:String = "hello there";
//this variable is available everywhere


function sums(){

var someN:Number = 5; //this is available only within this function due to using the var keyword
}

function sumMore(){

someN = 5; // as we have not used the var keyword it is just the same as defining this variable on the timeline that this function exists (although i woudnt recommend this method)
}


Hope this helps..

ah! so using "var bob" is sorta like using "_global.bob" and "_root.bob"
sorta being key word cuz i know they are different.
Am i on the right track?
yes or no?
