An object is a THING that encapsulates both data & methods to operate on
that data.

A data structure is simply an area of memory that has been given a specific
format.  There is no means for code to be attached to a data structure.

While I have no problem with people discussing object's in terms of RPG
futures, and interfacing RPG with other languages (like Java), abstract OO
programming discussion should be taken to a more appropriate forum... or
