Joyce is a programming language for parallel computers based on CSP and Pas-cal. A Joyce program defines concurrent agents which communicate through unbuffered channels. This paper describes a multiprocessor implementation of Joyce.

Family Planning Perspectives Through the mid-1980s, Medicaid eligibility requirements included very low income thresholds established by the individual states. Between 1987 and 1991, eligibility standards for poor and near-poor pregnant women were expanded dramatically. The 1986 Omnibus Budget and Reconciliation Act (OBRA) permitted states to extend eligibility (and receive reimbursement for se...

This paper describes a secure programming language called Joyce based on CSP and Pascal. Joyce permits unbounded (recursive) activation of communicating agents. The agents exchange messages through synchronous channels. A channel can transfer messages of different types between two or more agents. A compiler can check message types and ensure that agents use disjoint sets of variables only. The...

This article traces the history of Storyspace, the world’s first program for creating, editing and reading hypertext fiction. Storyspace is crucial to the history of hypertext as well as the history of interactive fiction. It argues that Storyspace was built around a topographic metaphor and that it attempts to model human associative memory. The article is based on interviews with key hypertex...
