The key to successful programming is finding the "right" structure of data and program. A programming language concept called module is presented here as a means to partition systems effectively. The module allows to encapsulate local details and to specify explicitly those elements that are part of the interface between modules.

Modules as presented here are part of the language Modula-2. Problems of separate compilation and of splitting a module into definition (interface) and implementation parts are discussed.
