This part documents the iso package which provides to Ciao programs (most of) the ISO-Prolog functionality , including the ISO-Prolog builtins not covered by the basic library. All these predicates are loaded by default in user files and in modules which use standard module declarations such as:
:- module(modulename,exports).
which are equivalent to:
:- module(modulename,exports,[iso]).
or
:- module(modulename,exports).
:- use_package([iso]).
If you do not want these ISO builtins loaded for a given file (in order to make the executable smaller) you can ask for this explicitly using:
:- module(modulename,exports,[]).
or
:- module(modulename,exports).
:- use_package([]).
See the description of the declarations for declaring modules and using other modules, and the documentation of the
iso library for details.
