If your file is called foo.pl, you can include it using
如果您的文件名为foo.pl，则可以使用它来包含它
:- [foo].
or, equivalently and a bit more explicit
或者，等效地，更明确一点
:- consult(foo).
or, if you're worried it may be loaded several times in a larger app
或者，如果您担心它可能会在较大的应用程序中多次加载
:- ensure_loaded(foo).
or, if you're using full-blown modules
或者，如果您使用的是完整的模块
:- use_module(foo).
though the exact name of the last predicate differs between Prolog versions.
虽然最后一个谓词的确切名称在Prolog版本之间有所不同。

If you want to include the file literally - similar to #include, use :- include('file.pl').
如果你想按字面意思包含文件 - 类似于#include，请使用： - include（'file.pl'）。
Most of the time it is preferable to structure your program using modules, though.
但大多数情况下，最好使用模块构建程序。
