- pointer: A variable in a language like C that contains the exact memory location of some other item. Perl handles pointers internally so you don't have to worry about them. Instead, you just use symbolic pointers in the form of keys and variable names, or hard references, which aren't pointers (but act like pointers, and do in fact contain pointers).
