Does this not work for you?

// Change the first instance only
var myPattern:RegExp = /sh/;
// Change all instances
//var myPattern:RegExp = /sh/g;
var str:String = "She sells seashells by the seashore.";
trace(str.replace(myPattern, "sch"));
// She sells seaschells by the seashore.

Hth,
Bob

Subject: [Flashcoders] Equivalent of setCharAt to change a character in a string

Probably something really simple but can't for the life of me recall the syntax 
to change a particular character of a string.

For example if I have the word "Flash" and want to change the letter "a" to an 
"e", I was hoping there was a function like setCharAt(2, "e");

Btw I am coding in AS3.

Thanks

paul
