Using SWI-Prolog Interactively - Output Taken off

I'm using SWI-Prolog interactively. When I run my query, I get a prefix of the output and the rest is taken off (marked using the string ...|...). Is this normal or should I go back and fix my program?

Nothing to worry about. It's just abbreviating it visually... just press 'w' (write) to display the complete internal representation of the list.

The number of items shown is controlled by a prolog flag. You can remove it by issuing

remove_max_depth:-
    current_prolog_flag(toplevel_print_options,Options), 
    select(max_depth(_), Options, NOptions)->
    set_prolog_flag(toplevel_print_options, NOptions); true.
