const are usually declared const becuase they are public or protected and accesible by other user or subclass and you wish to protect them with they const keyword so they cant be changed.
Inside a function that is a few lines of code written by yourself you dont normally have a problem in having to protect yourself from assigning a value to a variable again unless you have a split personality. Maybe you code like that all the time but I cant say I have seen that before... If you dont understand the diference between class members and function vars well... not much I can say.. --- In [email protected], "Paul Andrews" <[EMAIL PROTECTED]> wrote: > > ----- Original Message ----- > From: "reflexactions" <[EMAIL PROTECTED]> > To: <[email protected]> > Sent: Thursday, December 20, 2007 1:41 PM > Subject: [flexcoders] Re: const? > > > > Thanks for the advice, > > Maybe you could read the question, I am talking about Adobe declaring > > a const inside a function and asking what is the use and benefit of > > that. > > What is so different about using const inside a function?
