Checking a varaible if it's empty or set?

[_Jay]

I know in PHP there is a function to see if a varaible is empty or is set ( empty() and isset() ) I was wondering if there was a simular function in Flash?

Thanks.

null and undefined :)

do you mean...
if(var1){
trace(var1);
}else{
trace("var 1=undefined");
}
basically, if you just want to check if it has a value yet, then the above will do it.
