ALGOL 68
     
         An extensive revision of {ALGOL 60} by Adriaan van
        Wijngaarden et al.  ALGOL 68 was discussed from 1963 by
        Working Group 2.1 of {IFIP}.  Its definition was accepted in
        December 1968.
     
        ALGOL 68 was complex, and posed difficulties for both
        implementors and users.  It featured {structural equivalence};
        automatic type conversion ("{coercion}") including
        {dereferencing}; {flexible arrays}; generalised loops
        (for-from-by-to-while-do-od), if-then-elif-fi, an integer case
        statement with an 'out' clause; {skip} and {goto} statements;
        blocks; procedures; user-defined operators; {procedure
        parameters}; {concurrent} execution (cobegin/coend);
        {semaphores}; generators "heap" and "loc" for {dynamic
        allocation}.  It had no {abstract data types} or {separate
        compilation}.
