SNOBOL4

A quite distinct descendant of SNOBOL, developed by Griswold

et al in 1967. SNOBOL4 is declarative with dynamic scope.

Patterns are first-class data objects that can be

constructed by concatenation and alternation. Success and

failure are used for flow control. Delayed (unevaluated)

expressions can be used to implement recursion. It has a

table data type. Strings generated at run time can be treated

as programs and executed.
