Welcome to the sixth chapter of the FREE online programming course:
A Beginner’s 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: tutorials

Delphi 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.

   Some exercises for you...
Since this Course is an online course, there is much you can do to prepare for the next chapter. At the end of each chapter I'll try to provide several tasks for you to get more familiar with Delphi and the topics we discuss in the current chapter.

   To the next chapter: A Beginner's Guide to Delphi Programming
This is the end of the sixth chapter, in the next chapter, we'll deal with more sophisticated articles on the Delphi language.

If you need any kind of help at this point, please post to the Delphi Programming Forum where all the questions are answered and beginners are treated as experts.
