Let's say you have a set of names called set A. You also have a

way of comparing the sets?

By comparison, I mean finding the names that need to be added to
set B and deleted from set B to form set A.

Use Pascal, and then those are all primitive operations. I kid you
not.

Lots of languages have sets but Pascal's sets used to be so limited as
to be almost useless of general versions of the above problem. Does
modern Pascal have sets of anything more flexible that enumerated
types?
