whats the best way to make a statement run just once?  
at the begining of my movie i have a few default values i wish to be set, but only the 1st time thru, i have done this before by doing something like this

```auto
xxx=xxx+1
if(xxx==1){
///some stuff here

}

```

but this no longer seems to work with AS2.0 since it produces a NaN error  
any help appreciated , thanks
