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}.
