A procedure

Now, abstracting the "Hello, world!" into a procedure called "say_hello_world".

Note: That name may appear slightly different depending on the naming conventions of a language. Where possible, forward declarations are used.

Turing

procedure sayHelloWorld
   put "Hello, world!"
end sayHelloWorld

sayHelloWorld

{
