To be done
- This library is incomplete. As of SICStus 4.6.0, the following predicates are missing:
 samsort(+RawList, -Sorted) is det
Same as msort/2.
Compatibility
- SICStus 4
   57samsort(RawList, Sorted) :- msort(RawList, Sorted).
   58
   59:- meta_predicate samsort_3_key(2, -, +, +).   60samsort_3_key(OrderPred, Delta, E1, E2) :-
   61	% Intentionally never set Delta = (=),
   62	% because predsort removes duplicates
   63	% (i. e. if two items compare equal, one is removed),
   64	% but SICStus samsort doesn't.
   65	call(OrderPred, E1, E2) -> Delta = (<) ; Delta = (>).
 samsort(:Order, +RawList, -Sorted) is det
Similar to predsort/3, but the predicate Order is used to determine the order of terms. Order is called with two arguments, and if it succeeds, the first argument will be sorted before the second argument. Duplicates are not removed.
Compatibility
- SICStus 4
   76:- meta_predicate samsort(2, +, -).   77samsort(Order, RawList, SortedList) :-
   78	predsort(samsort_3_key(Order), RawList, SortedList).
 samkeysort(+RawList, -Sorted) is det
Same as keysort/2.
Compatibility
- SICStus 4
