The language was originally developed by Apple Computer as Clascal for the Lisa Workshop development system. As in most other modern OOP languages (including Java and C#), in Delphi a class-type variable doesn't provide the storage for the object, but is only a pointer or reference to the object in memory. There are dedicated reference-counted string types, and also null-terminated strings. [8] Metaclasses are first class objects. The origins of the Delphi programming language stem from an extension of the Pascal programming language, which was designed for use in the object-oriented programming arena, called Object Pascal. This code is called a Unit and is a Delphi module - one chunk of code. Strings can be concatenated by using the '+' operator, rather than using functions.
