Dynamic Instance Naming

Hello All
So here’s my problem.
I’ve created an array from XML elements.
I have my index saved in the var i

mc.index = i;

Now the problem I’m facing is dynamically changing a section of code.
I had to hardcode like this for now.

mc.onPress=function(){
if (this.index==0){
point0.frame._visible=true;
}
if (this.index==1){
point1.frame._visible=true;
}
}

When what I’d like to achieve is

 mc.onPress=function(){
point[this.index]._visible=true;
}

Any help on the syntax please!
