Yes, I use OO classes much like I used to use PL/I structures which, of course, are generalizations of C and Cobol structures. And classes have some additional advantages, e.g., can do serialization. And, what I really like is the name scoping. For what else is significantly different in encapsulation seems a little obscure. Maybe the biggie difference is not only have the data with name scoping, but also have the code, the methods, stuffed inside the class and making changes in the data in the properties of the class. Okay -- so get to use the class and its methods without keeping track of subroutines/functions separately. Okay.
