Copy animation from one object to another...... Like instance

Hi, I'm kind of new to maxscript.... i want to copy animation from one object to another... (General transformation Animation), But it should update on the fly Every time I update it on the main or master object. I want maxscript code for this... I searched for the scripts written by others (like KEy MOVER) but they bind animation on clicking the button... And everytime i make changes in master objects animation, i have to hit bind button.... i want to learn script but i stuked here.... and unable to move forward... this animation should also work after offsetting animation.... thank u in advance.... :)
