- But in another article you say:
-
- "behavior" is not a sequence of actions, it is a causal
- relationship between inputs and outputs. The [source] code
- [of a program] is the specification of this causal relationship.
-
- Now, it sounds from this like functional organization and
- "behavior" are almost the same thing. A specification of
- a functional organization would also specify the behavior.
