Snobol

Dating back to the 1960s, Snobol was the de facto standard text processing language in the mainframe era. Its text manipulation and program control mechanisms, based on hierarchical pattern matching and corresponding success/failure, compare well in effectiveness even with modern languages. In fact, Snobol can still be the tool of choice for tackling a number of text- and symbol-processing problems.
