SNOBOL

SNOBOL (String Oriented symbolic Language) is an unstructured, imperative programming language mainly intended for text processing and pattern matching, that was first designed and implemented at Bell Laboratories. SL4 and The Icon programming language are later developments of the SNOBOL language that add Pascal like structured elements to the language but have less powerful pattern matching features.

History
SNOBOL was developed by David J. Farber, Ralph E. Griswold and Ivan P. Polonsky at Bell Labs in 1962. An implementation with built-ins was SNOBOL2 in 1964. Programmer defined functions were added 1965 to SNOBOL3. Work on SNOBOL4 began in 1966.
