ICON is an imperative, procedural descendant of SNOBOL4 with a syntax reminiscent of C and PASCAL, but with semantics at a much higher level. It was written by Griswold et al to get around the GOTO-intensive style of SNOBOL. The OO extension is Idol.

Icon is a general-purpose language with special features for string scanning. Dynamic types. The central theme of Icon is the generator: when an expression is evaluated it may be suspended and later resumed, producing a result sequence of values until it fails. Resumption takes place implicitly in two contexts: iteration which is syntactically loop-like ('every-do'), and goal-directed evaluation in which a conditional expression automatically attempts to produce at least one result. Expressions that fail are used in lieu of Booleans. Data backtracking is supported by a reversible assignment. Icon also has co-expressions, which can be explicitly resumed at any time.
