Unload loadvariabels

1

Hi i have a fscommand that dose this:

function myFunction5() {
unloadMovieNum(7);
loadMovieNum(“bla.swf”, 22);
var tex = “Detta är ett dynamiskt textfällt.”;
myVars7.loadVariables(“bla.txt”);
stop();

How can I unload loadVariables(“bla.txt”); whit the next myFunction6 whit out putting a new loadVariables in? I cant find any unloadVariables
