Global functions

Hi,

I found this handy little function to pause the timeline


function paused(sec) {
   stop();   // action to pause
   var i = sec - 1;
   var t = setInterval(function () {
      if (i == 0) {
         clearInterval(t);
         play();   // action to continue
      }
      i--;
   }, 1000);
}

I need this function in several different frames in the timeline. How can I make this a ‘global’ function, so I only have to write it once and can use it wherever I want?
I did some googling and thought I could use the prototype thing, but I guess this is only for Movieclip functions?

Thnx in advance,

Grenouille.
