HALO --- a fuzzy programming language This paper deals with a fuzzy programming language, used in implementation of fuzzy intelligent systems. Borrowing from both high- and low-order languages, HALO (High And Low Order) integrates the symbolic programming and order-independent structure of expert systems with the conrol structures and procedural abstraction of Pascal. The HALO language is based on possibility theory and consequently, is well-suited to expert system development. HALO, probably best described as a ’fuzzy Pascal’, is simple to learn and use yet is powerful enough for complex artificial intelligence applications requiring structure, modularity, process control, and uncertainty management.
