  Objective C
       
           An object-oriented superset of ANSI C by Brad
          Cox, Productivity Products.  Its additions to C are few and
          are mostly based on Smalltalk.  Objective C is implemented
          as a preprocessor for C.  Its syntax is a superset of
          standard C syntax, and its compiler accepts both C and
          Objective C source code ({filename extension ".m").
       
          It has no operator overloading, multiple inheritance, or
          class variables.  It does have dynamic binding.  It is
          used as the system programming language on the NeXT.  As
          implemented for NEXTSTEP, the Objective C language is fully
          compatible with ANSI C.
       
          Objective C can also be used as an extension to C++, which
          lacks some of the possibilities for object-oriented design
          that dynamic typing and dynamic binding bring to Objective
          C.  C++ also has features not found in Objective C.
       
          Versions exist for MS-DOS, Macintosh, VAX/{VMS and
          Unix workstations.  Language versions by Stepstone,
          NeXT and GNU are slightly different.
       
          There is a library of ({GNU) Objective C objects by
          R. Andrew McCallum  with similar
          functionality to Smalltalk's Collection objects.  It
          includes: Set, Bag, Array, LinkedList, LinkList,
          CircularArray, Queue, Stack, Heap, SortedArray,
          MappedCollector, GapArray and DelegateList.  Version: Alpha
          Release.  ftp://iesd.auc.dk/pub/ObjC/).html">(ftp://iesd.auc.dk/pub/ObjC/).
