Hello :)
a delete in a function failed to destroy a variable ;)
My french article about this subject :
http://www.ekameleon.net/blog/index.php?2006/06/10/34--as-ssas-delete-un-peu-capricieux
Used google translator or bablefish if you want read my article in english
(sorry .. i speak english very bad...)
delete method returns false if the variable isn't clear on memory (protected
with a ASSetPropFlags or if the variable is undefined too)
function test() {
var a = 1 ;
trace("> a : " + a) ; // > a : 1
trace("i remove the variable 'a' : " + delete(a)) ; // output false
trace("> a : " + a) ; // > a : 1 // the value isn't deleted !
}
trace("++ delete sur une variable dans une fonction") ;
test() ;
.. you can read some good articles about Garbage collector (in FP8 and FP9
the garbage is better...)

You're welcome Micky
EKA,
I've been really confused by the garbage collection and how it sometimes
sits their coldly not doing the job ! I read somewhere the garbage
collection won't fire unless the application is in a still state. In an
application, that I had some interval process happening, the garbage
collection never worked and the memory usage kept going up. I've watched a
presentation by G Skinner, read some articles, but never found a way to
fire
that garbage collector other than minimizing the application (and that
works
in IE, it doesnt with firefox). So its an act of anxiety ! Can you point
us
to links where the garbage collection work ?, Perhaps with a new message
Thanks for your comment,
Yehia
