...Or if you like to perform a recursion (particular case of nesting). I do not belive there is a good way to re-declare a variable inside the scope of one function.
(?) You could comment out vars, copy/paste them with active code and uncomment when needed; it is more a text editor issue: //var x:Number; //var y:Number; //var a:Number; a = x + y; I think that splitting long function bodies into separate short ones is a better idea. All local variables may be declared (and not re-declared) inside these short functions: var x = calcA( calB() + calcC() ) / calcD(); g Friday, January 08, 2010 (1:18:45 PM) Cor wrote: > OOOh, indeed, that would be a bad choice. > -----Original Message----- > From: [email protected] > [mailto:[email protected]] On Behalf Of Paul Andrews > Sent: vrijdag 8 januari 2010 13:16 > To: Flash Coders List > Subject: Re: [Flashcoders] Declaring Function Variables > Cor wrote: >> Mmmm, I have never experienced any problems with it. >> > It just means you havent used the same variable in a loop with nested > functions that are also using the variable. >> -----Original Message----- >> From: [email protected] >> [mailto:[email protected]] On Behalf Of Paul > Andrews >> Sent: vrijdag 8 januari 2010 12:47 >> To: Flash Coders List >> Subject: Re: [Flashcoders] Declaring Function Variables >> >> Cor wrote: >> >>> Declaring it within a function will make the variable LOCAL (= usage in >>> >> that >> >>> function only). >>> You only declare it outside, once and (re)use it as often as you like. >>> >>> >> I would advise that it's best to avoid doing that.
