Object Pascal Introduction
Introduction (author: Tao Yue, state: negligible changes)
Welcome to Learn Pascal! This tutorial is a simple, yet complete, introduction to the Pascal programming language. It covers all of the syntax of standard Pascal, including pointers. If you're in a rush to get started, or if you're searching for information on a specific feature of Pascal, you can go directly to the Table of Contents to select any lesson in the tutorial.
I have tried to make things as clear as possible. If you don't understand something, try it out in your Pascal compiler and tweak things a bit. Pascal is a syntactically-strict language. This means that if you make a mistake, the compiler will stop and inform you of the error. Except when you're using files, there's practically no way for you to completely screw up your computer.
If you'd like to go into more depth or learn about topics beyond basic data structures, you can purchase books and magazines about Pascal programming which are listed in the wiki page Pascal and Lazarus Books and Magazines
To program in Pascal (or any high-level language, for that matter), you will need a compiler. You can use any standard Pascal compiler with this tutorial. If you need to download a compiler, or if you're new to programming altogether and don't know what a compiler does, check out the Compiler page.
