Free course : introduction to programming with Pascal / PDF
Sample of the PDF document
This tutorial is to get you started programming with
Pascal. By the end of the tutorial you should know how to run a simple Pascal
program. We will run a program which
displays “Hello World!” to the screen. We will also be using Free Pascal and
your computer’s command prompt; all of which will be explained.
About Pascal
Pascal I is a programming language invented in 1971 by
Dr. Niklaus Wirth. Named after the French mathematician and philosopher Blaise
Pascal, it is written to be easy to understand and compile. From the early
1980’s to 1999, Pascal was used in the Computer Science exam portion of the
Advanced Placement exam for high school students. This and the development of
the Turbo Pascal compiler helped increase the popularity of Pascal. Recently,
Pascal has lost much of its popularity to the language C++ (which is used by
Windows).
About File Mangers
A file manager is used to organize the files in your
computer. Files can be stored in File Folders (think of the file folders we use
to put paper in). File Folders can be stored in other folders, providing even
more levels of organization. For example you might have on your computer
several folders named, “Work”, “School”, and “Music”. In the “School” folder
you could have several more folders named “Math”, “Science”, “Reading”, etc.
and then in the “Science” folder you might have a bunch of files containing
your papers or reports for your science class. A file manager will often provide
multiple ways to navigate and organize your folders and files.
See http://en.wikipedia.org/wiki/Computer_file_management or http://en.wikipedia.org/wiki/File_manager for more information on file folders.
About Command Prompts
You can think of a Command Prompt as a way of
“talking” to your computer. You type commands into the command prompt window as
a way of “prompting” it to do certain things. We will be using the command
prompt to compile and run your program.

About Free Pascal
Free Pascal is a free open source compiler for Pascal.
“Open source” means whoever downloads it also has access to the code which was
used to write it. And “compiler” means it is used to change a programming
language which humans can understand (in this case Pascal), into machine
language which the computer can understand.....
