I FUTURE CAT WITH print_function
SO IM LIKE main OK?
    VISIBLE LOL Hello world /LOL
IZ __name__ KINDA LIKE "__main__"?
    main THINGZ

I don't get what this is.. but...
PHP:

<?
echo 'Hello, world!';
?>

C:

#include <stdio.h>

int main() {
    printf("Hello, World!");
    return 0;
}

C++:

#include <iostream>

int main() {
    cout << "Hello, world!" << "\n";
    return 0;
}

Java:

class HelloWorld {
    public static void main(String[] args){
        System.out.println("Hello, world!");
    }
}

C#:

public class HelloWorld {
   public static void Main() {
      System.Console.WriteLine("Hello World!");
   }
}

Not programming languages, but thought I might contribute.

JavaScript:

alert("Hello, World!");

Bash

echo "Hello, World!"

Matlab / Octave:

disp('Hello World!');

Pascal / Free-Pascal / Object-Pascal (Delphi):

program HelloWorld;

begin
  writeln('Hello World');
end.

Fortran:

program hello
   print *, "Hello World!"
end program hello

Also, see this wiki listing.

More,
Perl:

#!/usr/bin/perl

print "Hello, World!\n";

Python:

#!/usr/bin/python
print "Hello, World!\n"

SQL:

CREATE TABLE hello(
    s CHAR(10)
INSERT INTO hello ("Hello world")
SELECT *
    FROM hello

Html:

<html>
<head>
</head>
<body>
<p>
Hello,world
</p>
</body>
</html>

QBASIC

CLS
PRINT "HELLO WORLD"

GO:

package main
func main() {
    print("hello world")
}

Do you use GO at all? It looks interesting but I'm not really sure what it's for.
Ruby:

puts "Hello, world!"
commented: At the moment I'm just studing it, I'm considering GO for some backend jobs in web applications... +0

DOS

echo hello world

VB6

Print "Hello World"

VB.Net

Console.WriteLine("Hello World")

D programming language (Recently became interested in and loving it)

import std.stdio;

void main()
{
    writeln("Hello, world!");
}

how about you guys just type Hello and see what errors you get :)

or do this

//hello

If every one use one platform then it will be much easier for all to guess and manipulate but too much programs confuse even the tough and experts also.
