Now, Noc is installed so we can run programs. We are going to start with the “Hello,World” program.

Writing and Running a Noc program

Enter this following code in the hello-world.noc

def main = {
    "Hello, Noc!" print
}

it prints "Hello, Noc!"

Save the file and run the noc file like this:

$ noc hello-world.noc
"Hello, Noc!"

Anatomy of a Noc program

def main = {

}

We declare a ‘main’ function, this function is the first function that’s executed by Noc. Nothing (except comments but it’s ignored in parsing) is in the top-level, we write programs in functions. (see function-level).

"Hello, Noc!" print

And the ‘print’ function allows to print the text "Hello, World!" in the screen.
