Getting Multiple X and Y Coordinates

I have 12 clips on the stage. I want to get each one of their X and Y coordinates when they appear on stage. This will give a value to their starting position.

I will then use that starting position to create a reset function for them to obey after I rollout of each individual clip.

Confused?

loop for name of 12 clips (these are all named mc1, mc2, etc)
then
get the starting x and y coordinates for the clips
assign variable to the values (mc1x, mc1y, etc)

Thanks for help.
