Must I use in some way the threads?

That is exactly what Michael vC said in his mail.
In a  console application the main thread just starts, does some calculations and runs 
right until returning and with that terminates the program. If you want to so a longer 
living thingy, you need to hols the main thread e.g with sleep(). If during that time 
some "Event" needs to be handled, only a thread can do this.

This is not necessariliy how it has to be. I have lots of programs that have a 
simple endless loop with a delay() that checks for something in regular time 
slots:

repeat
   check something;
   delay(100000);
until false;
