Thanks for that idea. I've never used a task before but I modified a little program from the new book, Introduction to Ada Programming, 2nd ed., as follows:


procedure Hello_World_Task is
    task type Hello_Task;
    
    task body Hello_Task is
    begin
            delay 4.0;
    end Hello_Task;
        
    Task_1 : Hello_Task;
begin
    null;
end Hello_World_Task;


It still runs in the terminal.
