Help: "256 levels of recursion were exceeded in one action list."

[Roald Fernandez]

I'm trying to make this very simple mathematical flash-program that
factorizes a number. So far i have succeded, but flash dosent allow the
program loop more than 256 times is seems. I get this message:

"256 levels of recursion were exceeded in one action list.
This is probably an infinite loop.
Further execution of actions has been disabled in this movie."

Is there some way I can avoid this, or work my way around somehow?.


************************
The Actionscripting is as such:

var divident:Number = 2;
var tallToFactor:Number;
var tallToFactorOrig:Number;
var toFinish:Number;
var numbercount:Number = 0;

function fact():Void {
if (tallToFactorOrig == toFinish){
return;
}
else {
if (tallToFactor/divident == Math.floor (tallToFactor/divident)) {
trace (divident);
tallToFactor = tallToFactor/divident;
if (numbercount == 0) {
toFinish = divident;
numbercount++;
}
else {
toFinish *= divident;
}
fact();
}
else {
if (divident == 2) {
divident++;
fact();

}
else {
divident += 2;
fact();

}
}}}

mcButton.onPress = function():Void {
divident = 2;
tallToFactor = tNumberType.text; //tNumberType is a input textfield where
the number to factorize is typed
tallToFactorOrig = tNumberType.text;
fact();
}

Given the code, the acion-scripting only allows numbers that have prime
numbers up to 503. Wich makes sence regarding the 256 times loop-limit,
since the program tests numbers with the increment of 2.

Id much appreciate if anyone knows some whay to get around the loop-limit.
Im very familiar with actionscript so, please, any help would be great.

Typo there...
I'm not very familiar with actionscripting

that's tail end recursion, so you should be able to rewrite your function as
a loop (instead of being recursive).

ahhhhh! ... mathematics ... my favorite ...

have you tried to write a NON-RECURSIVE version of the fact():Void
function? a non-recursive version would most probably be using 'do'
or 'while' or 'for' loop of some sort.
