A quick pascal tutorial for programmers.
-By Anman

Here is the basic structure of a pascal program.

program programname(input,output);
begin
end.

Begin and end. signify the beginning and ending of the program.

Variables:
There are many types of variables in Pascal. Here are a few.
	String(non-standard)-Stores an array of characters.
	char - One character (0-255)
	int - An integer (0-32675)
	real - A floating point number(very big)
	longint - A 32-bit integer(0-4 billion)
	double - The largest floating point number

Variables are declared as follows.
	var variablename:variabletype;

Note: You cannot declare variables inside a begin and end block.

Output:
Output in Pascal is fairly easy. All output in Pascal is handled in the writeln and write procedures.

Example:
writeln("Welcome to Pascal"); <-- This line will write Welcome to Pascal and then line-feed.
write("Welcome to Pascal");   <-- This line will write Welcome to Pascal.

If you wanted to output a variable to writeln or write you would do it like this:
writeln("This is" ,nameofvariable ,"Pascal");

Input:
Input in Pascal is almost as easy as outputting. All input is handled in two procedures: read and readln.

Example:
readln(variablename); <--This line will keep reading until you press a line-feed.
read(variablename); <--This line will keep reading until you press a key.

Let's put this altogether in a program.

program inputoutput(input,output);
	age:integer;
	begin
		write("Enter your age: ");
		readln(age);
		writeln("Wow I wish I was that old.");
		write("How old are you really?");
		readln(age);
		writeln("That is what I thought");
	end.
