Abstract vs. Interface - separating definition and implemention in Delphi?

The key to understanding this is to realize that it's about more than just definition vs. implementation . It's about different ways of describing the same noun.

I doubt that this is a question of "better approach" - they just have different use cases.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
