Pointers in Delphi

Pointers can be still used in pascal and i think they may preserve it until delphi is alive.

Even though i have used pointer when i am learning pascal. I still can't understand the real use of pointers, I manage to do all my delphi programs without it.(by some other ways)

what is the real use of pointers. And I am asking for real world usage, and can we manage to do anything without pointers.
