targeting duplicated movieclips 1

[miguelisboa]

i'm drawing (based on an elipse) and using this code:
duplicateMovieClip(ponto, "ponto" + i, this.getNextHighestDepth());
i varies from zero to 359, so how can i target every (or any) of the recent created mcs?
my prob is the duplicated movie clip's name! how to write it?
if i use ("ponto" + i) i get a String, not my mc.
Any help would be apreciated!

without seeing more code hard to be exact but try

this["ponto"+i]

bingo!
i just tried:
trace(this["ponto"+i]._x);
this["ponto"+i]._alpha=random(100);
and works perfectly

thanks a lot!
BTW where could i have learned that sintax (this[blabla])?
