Downloaded and installed the "stable" version (1.14) on Ubuntu and tried to run code that works fine on SWI-Prolog. One predicate used is call/1 and Ciao places that in a library hiord_rt that doesn't appear to be included in the stable version. How do I get and install that library? Or is there a workaround? I want to use it in the following code that adds list comprehensions to Prolog.
%-------------------------------------------------------
%% list comprehension defined
:- op(700, xfx, [ <- ]).
:- op(450, xfx, [ .. ]).
:- op(1100, yfx, [ & ]).
Y <- M .. N :-
integer(M),
integer(N),
M =< N,
between(M, N, Y).
Z <- {Var & Dec & Pred} :-
findall(Var, maplist(call, [Dec, Pred]), Z).
