Mika

Hello to all, I would want to use 'statistics(walltime, [T, _ ])'
of SICStus Prolog in Swi Prolog but Swi Prolog does not
recognize the word key ' walltime'.
How I can make?

In swi-prolog,
| ?- statistics(cputime,X).

Where X is the time in seconds, since Prolog was started (X is float).

You need SWI's real_time for walltime.
cputime is just cputime which usually is different from the time on your wall clock.

Do

?- help(statistics).
