scaleX & scaleY props question

programming flash

what is the right way to use the scaleX and scaleY properties? I don’t quite understand how to use them…
right now, I’m using this, but I think scaleX and scaleY would be a better idea:


if(*condition*){
some_mc.width++;
some_mc.height++;
}
else{
some_mc.width--;
some_mc.height--;
}
