Using Variables for Instance Names

Hi,

I'm hoping someone can help me understand the right way to do this. Basically I have some programmatically attached movie clips which are attached in a loop, so the only way I can reference their Instance names is through using a variable. I want to do this so that I can attach a createTextField to each clip instead of _root which is what I do now For example I'm tring to do this:

for (i=0;i<5;i++){
clip2 = _root.attachMovie("A","A"+i,{_x:coordx,_y:coordy});
Variable-which-is-named-("A"+i)-here.createTextField("_text"+i,depth,coordx+5,coordy+5,40,30);
}

I hope that makes sense? If anyone can point me in the right direction I'm not having luck with google searches

Best Regards,
Tom
