Does Actionscript have something like magic constants?

Question

Yes, I am new to Actionscript/Flex/Flash, but I'd really like to call something like C/C++/PHP/etc magic constants like:

__FUNCTION__
__LINE__
__FILE__

Is there an equivalent in Actionscript 3.0? When compiling, I get the error:

Error: Access of undefined property __FUNCTION__.

I'd like to identify what function, line and file are currently executing. — randomx, Sep 01 '11 at 22:32

@randy Jacob's answe covers a big chunk. I'd also recommend looking into the debugger if you haven't already (comes with the Adobe products, but I'm not sure which poison you chose). — Jacksonkr, Sep 02 '11 at 02:23
@Jacob - thanks, I will deal with a full stacktrace, if that's as close as I can get. — randomx, Sep 02 '11 at 03:55

There is a special object named arguments accessible in each function. It can be used to get arguments (as the name already implies):

arguments[0] // first argument

It can also be used to get you a reference to the called function:

arguments.callee

In earlier Actionscript versions there it also had a caller property, but not in AS3 any more.

There is a way to get the name of a function using the callee property: Actionscript - Obtain the name of the current function

This may be as close as it gets for AS3. +1 – randomx Sep 02 '11 at 21:07
Side note: `arguments[0]` will online work **inside** a function block that has at least one parameter. Just some clarification for those that are really really new. +1 for being more enlightened than me. – Jacksonkr Sep 03 '11 at 15:17
