A set is an "array" (scientific English, not Pascal syntax) of bits 
(i.e. boolean values) supported by special operators.

(Remember: Boolean Algebra and Logical Algebra are mathematically 
equivalent).

The "Set" stuff is correctly done and "nice in Pascal, but in most cases 
I know, set type variables s are used not to represent real-world  sets 
but real world arrays of logical  values.
