I have this problem.
I got an array. In these array are stored some functions like :

var ar:Array = new Array("Math.sqrt(Math.pow(BC,2)-Math.pow(AC,2))", "BH*BC");

then i have the variables BC, BH, AC:

BC = 5;
BH = 5;
AC = 5;

Now, how can i evaluate ar[0] with the correct values? I tried with value(), eval() and some other functions, but it doesn't work. (returns "undefined")
I used to do that with eval() or do() in Lingo (Macromedia Director), but now i have to do that in flash and I can't solve this problem.
Anybody can help?

Thanks.
Emanuele.

eval in actionscript doesn't work that way
store your functions… as functions:

var BC = 12;
var BH = 6;
var AC = 3;

var functions = {};

functions.foo = function(a, b) {
	return Math.sqrt(Math.pow(b, 2)-Math.pow(a, 2));
};

functions.bar = function(a, b) {
	return a*b;
};

// this gets hard to read! first way is best
//var functions = {foo:function (a:Number, b) {
//return Math.sqrt(Math.pow(b, 2)-Math.pow(a, 2));
//}, bar:function (a, b) {
//return a*b;
//}};

trace(functions.foo(AC, BC));
trace(functions.bar(AC, BC));

if you require something different - allowing a user to type in a function for example - you'll need to parse the input, which may not be trivial

Thanks for the help. Anyway I had to parse it to make it work
Bye.
