Thanks Danny,

My error was simply that I inadvertently used the same name for a method 
(function) in the derived class that I had already used in the parent class.
The result was then a very obscure error because the wrong calculation 
was performed and later on an array was empty.
Fortunately, thanks to you very generous tutors I have learned to read 
the error trace very carefully indeed.
Thanks a lot.
Sydney
