[fpc-pascal]Why Oop?

[gj bart]

     I've yet to figure out why Object-Oriented programming is so
important.  If I want to, say, write a program that simulates the game of
blackjack, I just need the data, some shuffle routines, some decision
tables, etc.  All this stuff about making objects and ancestors just seems
superfluous.  If I am to use the routines later well, isn't that what a
library is for?

     Obviously I'm missing something but I'm not clear what it is.  Aside
from perhaps helping coordinate projects involving several individuals,
what's the advantage?
