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! $
End article.
