Use function details outside function

Hi,

I am using this function/code to get marker text. I want to use the output of this function in another function which I am unable to do so.

Is there a way to store/use the text2 outside this function?   

#target framemaker

var doc, marker, nextMarker, regex, text2;

regex = /^newlink Filename\:.*/;

doc = app.ActiveDoc;

function getMarker(doc, text2){
marker = doc.FirstMarkerInDoc;
while (marker.ObjectValid () === 1) {

    nextMarker = marker.NextMarkerInDoc;

    if (marker.MarkerTypeId.Name === "Hypertext") {
    
        if (regex.test (marker.MarkerText) === true) {
    
			text2 = marker.MarkerText;
	
        }
    }
	
    marker = nextMarker;
	
}
}

alert (text2);
