    (SNOBOL) A string processing language for text
   and formula manipulation, developed by David J. Farber, Ralph E.
   Griswold and Ivan P. Polonsky at Bell Labs in 1962.
   SNOBOL had only simple control structures but provided a
   rich string-matching formalism of power comparable to regular
   expressions but implemented differently.  People used it
   for simple natural language processing analysis tasks well
   into the 1980s.  Since then, Perl has come into favour for
   such tasks.
   SNOBOL was originally called "SEXI" - String EXpression
   Interpreter.  In spite of the suggestive name, SNOBOL is not
   related to COBOL.  Farber said the name SNOBOL was largely
   contrived at the time the original JACM article was published
   when one of the implementors said something like, "This
   program doesn't have a snowball's chance in hell of ...".  The
   expansion to "String Oriented Symbolic Language" was contrived
   later.
   Implementations include (in no particular order): SNOBOL2,
   SNOBOL3, SNOBOL4, FASBOL, SITBOL, MAINBOL, SPITBOL
   and vanilla.
