  From  The  Free  On-line  Dictionary  of  Computing  (13  Mar  01)  [foldoc]: 
 
  pointer 
 
  1.    An  {address},  from  the  point  of  view  of  a 
  programming  language.  A  pointer  may  be  typed,  with  its  {type} 
  indicating  the  type  of  data  to  which  it  points. 
 
  The  terms  pointer"  and  reference"  are  generally 
  interchangable  although  particular  programming  languages  often 
  differentiate  these  two  in  subtle  ways.  For  example,  {Perl} 
  always  calls  them  references,  never  pointers.  Conversely,  in 
  C,  pointer"  is  used  although  "a  reference"  is  often  used  to 
  denote  the  concept  that  a  pointer  implements. 
 
  {Anthony  Hoare}  once  said: 
 
  Pointers  are  like  jumps,  leading  wildly  from  one  part  of  the 
  data  structure  to  another.  Their  introduction  into  high-level 
  languages  has  been  a  step  backwards  from  which  we  may  never 
  recover. 
 
  [C.A.R.Hoare  "Hints  on  Programming  Language  Design",  1973, 
  Prentice-Hall  collection  of  essays  and  papers  by  Tony  Hoare]. 
 
  2.    (Or  "mouse  pointer")  An  {icon},  usually 
  a  small  arrow,  that  moves  on  the  screen  in  response  to 
  movement  of  a  {pointing  device},  typically  a  {mouse}.  The 
  pointer  shows  the  user  which  object  on  the  screen  will  be 
  selected  etc  when  a  mouse  button  is  clicked.
