Object-Oriented Programming (OOP)

One difference between the handling of computer machine code and local variables prior to the 1990s and the handling of that same code and variables after the advent of OOP is this: Before the 1990s, the code to support a given window stood apart from the storage locations for variables used in that code. The code was put into machine code form at the time of compilation and was used throughout the execution of the project. Its local variables were stored elsewhere. With OOP, both the code and its local variables are bundled into one packet and are recreated by the PC s operating system each time the packet is needed. OOP works wonderfully so long as the PC has lots of memory and the project is equipped with a garbage collector that destroys old, unused packets and makes the old memory locations available to the operating system. The Visual C# compiler uses OOP exclusively in its output formulation (creating the intermediate code that is transformed into machine code by a special cookie on one s computing machine).
