1. iCOMP Intel Comparative Microprocessor Performance index Icon A descendant of SNOBOL4 with Pascal-like syntax, produced by Griswold in the 1970s. Icon is a general-purpose language with special features for string scanning. It has dynamic types: records, sets, lists, strings, tables. If has some object oriented features but no modules or exceptions. It has a primitive Unix interface. 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. Version 8. 8 by Ralph Griswold arizona. edu> includes an interpreter, a compiler for some platforms and a library v8. 8. Icon has been ported to Amiga, Atari, CMS, Macintosh, Macintosh/MPW, MS-DOS, MVS, OS/2, Unix, VMS, Acorn.
