If you ever used the "makelink" command from the CLI then you know how to use pointers. If you don't know how to use it then it might help to look at any AmigaDOS documentation you might have on it.
For a more complete idea of how pointers work: "hard" links are like references in C++ and "soft" links are like standard pointers in C.
Some of the most useful uses of pointers are linked lists and trees. Both of which you should get familiar with in a hurry because linked lists are used everywhere in AmigaOS and trees are used in directory structures.
