## Examples

An example where an hypothetic application would have some limitations that the user should be made aware when running on a backend Prolog compiler with bounded arithmetic:

    :- if(current_prolog_flag(bounded, true)).

        :- initialization(
            logtalk::print_message(warning,app,bounded_arithmetic)
        ).

    :- else.

        :- initialization(
            logtalk::print_message(comment,app,unbounded_arithmetic)
        ).

    :- endif.
