  Smalltalk 
 
    The  pioneering  {object-oriented  programming}  system 
  developed  by  the  Software  Concepts  Group  led  by  {Alan  Kay}, 
  at  {Xerox  PARC}  in  1972.  It  includes  a  language  (usually 
  interpreted),  a  programming  environment,  and  an  extensive 
  object  library. 
 
  Smalltalk  took  the  concepts  of  {class}  and  {message}  from 
  {Simula-67}  and  made  them  all-pervasive.  Innovations  included 
  the  {bitmap  display},  windowing  system  and  use  of  a  {mouse}. 
 
  The  syntax  is  very  simple.  The  fundamental  construction  is  to 
  send  a  message  to  an  {object}: 
 
  object  message 
 
  or  with  extra  parameters 
 
  object  message:  param1  secondArg:  param2  ..  nthArg:  paramN 
 
  where  "secondArg:"  etc  are  considered  to  be  part  of  the 
  message  name 
 
  Two  pseudo-variables  are  defined:  self"  -  the  receiver  of  the 
  current  message  and  super"  -  an  object  of  the  current  class's 
  {superclass}.  Smalltalk  does  not  have  {multiple  inheritance} 
  so  each  class  can  have  at  most  one  superclass. 
 
  Early  versions:  Smalltalk-72,  Smalltalk-74,  Smalltalk-76 
  (inheritance  taken  from  Simula,  and  concurrency),  and 
  Smalltalk-78,  {Smalltalk-80}.  Other  versions:  {Little 
  Smalltalk},  {GNU  Smalltalk},  {Smalltalk/V}.

  interpreters}.
