ActionScript 2.0 :: Triggering Arrays - Hold Co-ords - Scale - Rotation

Im creating an array to hold co-ords, scale, rotation, etc for a menu system. I'm having trouble working out the best way to tell it that its current position is, say, mc_A and now it should show, say, mc_D. At present in my array I have a status parameter which is set to true if its the current movieclip, so mc_A is true. Now mc_D is triggered, what is the best way to tell the array that now mc_D is true and mc_A is now false. I understand that I could just have a line saying _root.myMenuArray[0].status = "false"; before I call_root.myMenuArray[4].status = "true";
