n = oItem.IniX
The initial position means the position/size of the object as it was drawn in the graphics editor. This is a static value in the configurators regardless on the possible data binding (not the first evaluation of data binding).
X=0, Y=0 means the left upper corner of the parent Pmg object.
var oItem = pMe.Items("/Txt0");
var nIniX = oItem.IniX;
