Hi Viktor,
thank you for your answer. The reason I used the "for - iteration": I need
associative Arrays.
But they are nothing than Objects, so I now changed a= new Array() to a =
new Object(); and the iteration works as expected :-)
But good to know for the future to avoid assoziative arrays as
array-decraration.
