3 Modules

ALS Prolog provides a module system to facilitate the creation and maintenance of large programs. The main purpose of the module system is to partition procedures into separate groups to avoid naming conflicts between those groups. The module system provides controlled access to procedures within those groups. The ALS module system only partitions procedures, not constants. This means that the procedure foo/2 may have different meanings in different modules, but that the constant bar is the same in every module.
