High‐level goal‐directed concurrent processing in icon

摘要

AbstractConcurrent language features have been added to an experimental dialect of Icon called Conicon. These new language features allow Icon to deal with new application domains such as intelligent robot control and real‐time natural language processing. Besides widening the scope of Icon's intended application domain, these experimental concurrent processing notations also encourage programmers to revise existing programs to take advantage of the new language capabilities. For example, concurrent evaluation of the alternative arms of compound goal‐directed expressions is now possible. This paper describes these concurrent processing notations and presents several examples of their expressive po
