A Beginners Guide to Delphi Programming.
Before you start developing more sophisticated applications by using the RAD features of Delphi, you should learn the basics of the Delphi Pascal language.
Delphi Language: tutorialsDelphi language, a set of object-oriented extensions to standard Pascal, is the language of Delphi. Delphi Pascal is a high-level, compiled, strongly typed language that supports structured and object-oriented design. Its benefits include easy-to-read code, quick compilation, and the use of multiple unit files for modular programming.
Here's a list of tutorials, an introduction to Delphi Pascal, that will help you learn Delphi Pascal. Each tutorial will help you to understand a particular feature of Delphi Pascal language, with practical and easy to understand code snippets.
