Im quite new to flash
I have been working on a media player that plays external swf files
Theres 3 buttons , play stop and pause

The script for the play button is-

Actionscript Code:
on (press) {
    loadMovieNum("filestart.swf",1);
}

And the stop button script is-

Actionscript Code:
on (press) {
    unloadMovieNum(1);
}


This works ok
But I want to be able to pause the playback as well
How do I accomplish that?
