Delphi Basics
	This web site provides help and reference for the fundamentals of the Delphi© language. It gives an introduction to the Delphi Object Oriented Language for newcomers, and provides a ready reference for experienced programmers. It limits itself to a broad base of the language in order to keep things simple and manageable. The approach taken is to present the most useable basics of Delphi Programming in as accessible a manner as possible. Feel free to contact the author about any aspects of the site. Every effort will be made to respond to all emails received.
