In this article we will try to cover the very basics of Pascal and we will leave OOP for the next issue. (continua)
Abstract classes and interfaces

Errors were considered something that happened, and debugging was an activity that took place once evidence of an error appeared. (continua)
This article is an introduction to OOP in Delphi. It will not teach you OOP – we assume you are already familiar with it –, but it will show the basics of working with classes in Object Pascal. (continua)
