>Following proper OOPS techniques, Thomas Ganes suggestion is the correct one. Create a second method in A and override it in B. When the Init calls the method, it will call the local version. If you need the B of the local method to call the parent version, then use DODEFAULT().

Thomas and Marcia suggested this technique. We're also using hook methods.

So, line 10 will become a separate method in the Base class and the derived class would only need to overwrite one method. Hopefully line 10 can be easily created as a separate method.

Otherwise I would use Borislav's idea of invoking this line conditionally based on some property.

In either case, this assumes that we would need to change class A.
