If you take a typical program and look at it, it's just a string of 
characters: opcodes and operands.   However, some of these substrings 
represent functions that get called from different sorts of callers on 
behalf of a range of higher-level purposes (e.g. a call to allocate 
memory or a thread of execution).

With a Unix shared library, for example, even many of the physical 
memory parts are shared across independent systems.
Self-referential logic is contained in an assembly, exposing some 
symbols, and then different client programs (rules outside it's 
definition) drive it via these symbols -- a.k.a user applications.
