NetScript is an environment for scripting with network components. The NetScript environment’s scripting language, which is an extension of the BASIC programming language, is deliberately kept simple, so the scripts are relatively easy to write and modify. In NetScript, a developer selects required components from a distributed catalog and then writes a script invoking methods on the components as if the components are local. When a script is launched, the NetScript run time determines component sites in the network and transparently moves the script as needed.
