>Encapsulation has nothing to do how you store source code. The important aspect of encapsulation is, if you build a class, that internal values and methods are hidden to the outside. When building the class, you carefully evaluate what the actual interface will be, while you present an absolut minimum of values and methods to the calling objects.

I recognize that encapsulation is an aspect of object orientation. But the general definition of encapsulation goes beyond that one use.

It also relates to any process, mechanical or otherwise, which aggregates things (data or functions) under one umbrella. This includes encapsulating utility functions into utils.prg, and close month processing functions into close_month.prg, and other such aggregations.

To say such things are not encapsulation is to use too narrow a definition, and to not recognize the root use of the word and its meaning in English.
