Now let's write a "hello world" program and compile it using voc.

Create a new file named foo.Mod and insert in it the following code.

MODULE hello;

IMPORT Console;

BEGIN

Console.String ("Hello World!");
Console.Ln;

END hello.

Which means

MODULE hello — The module's name is hello.

IMPORT Console — Import the module Console.

BEGIN — Here we start our code!

Console.String ("Hello World!"); — Module Console, Procedure String (which is going to show a sting on our console) Hello World!
Console.Ln; — Print a line on the Console.

END hello. — End of the module hello, and let's not forget the dot. (:

Now let's compile it!

voc -m foo.Mod

and now let's run it!

$ ./hello
Hello World!

$
