Can someone explain me what the “in” means in this bit of code?

function select(){  
for(i [COLOR=red] **in** [/COLOR] playlist\_mc.target\_mc){  
if(playlist\_mc.target\_mc\*.songNum != songNum){  
playlist\_mc.target\_mc\*.gotoAndStop(1);  
}  
else{  
playlist\_mc.target\_mc\*.gotoAndStop(2);  
}

```
}

```

}

thanks,  
Stanley

(looking it up in the flash-helpfiles is a bad idea, the result is like 2763 topics 🙂 )
