APL2 implementation of cross-system shared variables
James A. Brown, Erik Kane · ACM SIGAPL APL Quote Quad · 1992
This paper discusses the requirement for intermachine communication and how this requirement is met with APL2's cross-system shared variables. One problem encountered in the design is the mapping of APL2's cooperative peer-to-peer communication model onto a client server data transport mechanism. Another is the ability of APL2's sharing mechanism to address applications on other machines. The goal of the facility is to provide a high level of communication between applications running on different machines while introducing the minimum language extension.
