Change script from CS4 to CS6

Hi,

I need to change this script from CS4 to CS6:

myRoundCornerLeftBottomVerticalGreen = myDoc.graphicLines.add (myDoc.layers.item ("Die"));
myRoundCornerLeftBottomVerticalGreen.geometricBounds = [myPageHeight/2, ".125 in", myPageHeight-.125,  ".125 in"];
myRoundCornerLeftBottomVerticalGreen.strokeColor = myDoc.colors.item("Proof");
myRoundCornerLeftBottomVerticalGreen.strokeWeight = "1pt";

var myPathPoint = myRoundCornerLeftBottomVerticalGreen.paths.item(0).pathPoints.add (myDoc.layers.item ("Die"));
myPathPoint.anchor = [myPageWidth/2, myPageHeight-.125];
myRoundCornerLeftBottomVerticalGreen.cornerOption = CornerOptions.ROUNDED_CORNER;
myRoundCornerLeftBottomVerticalGreen.cornerRadius = ".125 in";

Thank you.
