Networking has turned computers from isolated data
processors into powerful communication and elaboration
devices, called global computers; an illustrative example is
the World–Wide Web. Global computers are rapidly evolving
towards programmability. The new scenario has called
for new programming languages and paradigms centered
around the notions of mobility and location awareness. In
this paper, we briefly present X-KLAIM, an experimental
programming language for global computers, and show a
few programming examples
