  Icon
  
      A descendant of SNOBOL4 with Pascal-like
     syntax, produced by Griswold in the 1970's.  Icon is a
     general-purpose language with special features for string
     scanning.  It has dynamic types: records, sets, lists,
     strings, tables.  If has some object oriented features but
     no modules or exceptions.  It has a primitive Unix
     interface.
  
     The central theme of Icon is the generator: when an expression
     is evaluated it may be suspended and later resumed, producing
     a result sequence of values until it fails.  Resumption takes
     place implicitly in two contexts: iteration which is
     syntactically loop-like ('every-do'), and goal-directed
     evaluation in which a conditional expression automatically
     attempts to produce at least one result.  Expressions that
     fail are used in lieu of Booleans.  Data backtracking is
     supported by a reversible assignment.  Icon also has
     co-expressions, which can be explicitly resumed at any time.
  
     Version 8.8 by Ralph Griswold  includes
     an interpreter, a compiler (for some platforms) and a
     library (v8.8).  Icon has been ported to Amiga, Atari,
     CMS, Macintosh, Macintosh/MPW, MS-DOS, MVS, OS/2,
     Unix, VMS, Acorn.

From The Free On-line Dictionary of Computing (30 December 2018) :

  icon
  
      A small picture intended to represent something (a
     file, directory, or action) in a graphical user interface.
     When an icon is clicked on, some action is performed such as
     opening a directory or aborting a file transfer.
  
     Icons are usually stored as bitmap images.  Microsoft
     Windows uses a special bitmap format with file name extension
     ".ico" as well as embedding icons in executable (".exe") and
     Dynamically Linked Library (DLL) files.
  
     The term originates from Alan Kay's theory for designing
     interfaces which was primarily based on the work of Jerome
     Bruner.  Bruner's second developmental stage, iconic, uses a
     system of representation that depends on visual or other
     sensory organization and upon the use of summarising images.
