Yes, indeed:
| ?- ['Tutorial0'].
compiling /home/cspal/Emacs/Prolog/Tutorial0.pro for byte code...
/home/cspal/Emacs/Prolog/Tutorial0.pro compiled, 4 lines read - 540
bytes written, 10 ms
yes
| ?- ['Tutorial0.pro'].
compiling /home/cspal/Emacs/Prolog/Tutorial0.pro for byte code...

yes
| ?-
So my mistake was that that I don't put the file name between '

When I follow this abowe, it hangs forever:

compiling user for byte code...
