The simplest "hello" that works with Quartus and ModelSim

I wanted to make a step-by step tutorial, which really works with Quartus and ModelSim.

By trial-and-error method, I came to the result, of making the files Hello_tb.v

module Hello_tb;    reg clock,reset;
    initial
        begin
            $display("Hello world!");
            $finish;
        end
        
        Hello dummy(clock, reset);
endmodule

and Hello.v

module Hello(input clk, input rst);endmodule

My questions are:

1./ Is this the possible minimum for the Hello, which works for Quartus+ModelSim combination?

2./ The "$finish" produced warning "ignoring unsupported system task in the "Analyzis and Elaboration" phase ;

and a note "Note $finish" in ModelSim simulation. So, obviously it is not ignored. What is really the case here?

(I mean: what is ignored and what is not? And, why this misleading message? And, why a standard task is said to be

not supported?)

3./ During simulation, when "$finish" is reached, in a popup window I am asked if I really want to finish.

If I say yes, the simulator window closes.

As I just want to see the result in the "Transcript" window, I say "No" and I can browse the messages in the window,

but also the simulation continues. Is it the intended behaviour?

Thanks for your opinion in advance.
