Hi Dave and all,

My eyes failed me spotting the bugs :-) They are just staring at me
yet i miss to catch them. I guess thats the net result when one take
it too seriously haha (joke).

I fully agree function is not called when the parenthesis is missing,
you only call the object. About Pascal or VB i cant comment on them
:-)

The code works as expected now. I guess i have to move on to the other
examples.

Will be back here to bug you guys with questions :-) Thank you for so
helpful.
