This work is an overview of the evolution of language very dear to the author because she was the first to study at the time of her school study, Pascal.

In the opinion of many, this dated language still surprises us with modern development platforms such as Dev-Pascal, Delphi and Lazarus. In this book we focus first on Pascal in general and on the application of some simple addition and sorting programs in Dev-Pascal and then dedicate ourselves to a more complex platform that also allows the creation of visual applications with the insertion of Form integrated with the language Pascal, Lazarus.

Finally we are dedicated to the design and creation of databases and we integrate them into Lazarus applications.

With these notions you will be able to create Pascal programs and applications in Lazarus for the solution of the most varied problems.
