The Network Shared Variable (NSV) and Network Shared Variable Processor (NSVP) provide a user signed on to a local SHARP APL system with the ability to communicate with a remote SHARP APL system over a communications interface by sharing a variable with a task on that remote system. More specifically, NSVP extends the shared variable protocol to allow communications between tasks on different computer systems.Together, they represent dynamic innovations in APL technology that provide greater computing flexibility and power to the end user and the data centre. NSVP encourages users to maximize the potentials of distributed applications as it helps organizations optimize their data centre resources. NSVP also reinforces the image of APL at the forefront of system software technology.The NSV, while transparent to the user after coupling, enables users to access data from other systems using just one set of commands, while it minimizes the human and hardware resources required to maintain the data centre.In several ongoing tests of the NSV prototype, the product has proven its value to a variety of organizations around the world with substantially different needs.
