Co ordinate system

Hi , 
I have two robots of same model facing each other , they have different Controllers , both are faced at a distance of 40 M on a single track , the 0 degree for the seventh axis is at the middle of the track. I would like to have the same world co-ordinates for both the Roboters. I have teached the positions for one Roboter and would like to use the same  rob Targets for the second Roboter. I think if I have same world co ordinates for both the Roboters then I can use the same rob Targets to reach the Position.

1. How do I Change the world co ordinates of the Roboter , is it the Task Frame ?
2. MirrPos function is not working 
 pdummy2:= MirPos(pdummy,wobj0); \\ Here it is only converting mirror of XY plane and on the Wobj0 


Thank you
