Idiom #3 Create a procedure

Like a function which doesn't return any value, thus has only side effects (e.g. Print to standard output)

fn finish(name: &str) {
    println!("My job here is done. Goodbye {}", name);
}

The actual return type is Unit, typed '()' and can be omitted from function signature.
procedure Finish (Name : String) is
begin
   Put_Line ("My job here is done. Goodbye " & Name);
end Finish;
