You are assuming that a pointer is a lower level construct, that is, 
a machine address. Whether this is true depends on the context. If an
assembly language programmer speaks about pointers, he or she probably
means address words. A Pascal programmer might use the word to designate
the high level reference type of that language.

An access type is basically a pointer. You can say that a URL embedded in
someone's web page is also a pointer of sorts.
