Location transparent distributed scripts and their execution system on D´Agent

Ease of programming is the main merit of script languages. In distributed computing environments, programmers need to be aware of locations of resources and need to write additional codes for using remote resources in scripts. This makes scripts more complicated than those which use only local resources and cancels out the merit of script languages. We propose a virtual single computer model on which programmers needn´t be aware of locations of resources. Programmers write scripts which use remote resources and scripts which use only local resources in the same way. We developed a prototype system which executes such scripts. The system is implemented on the existing mobile agent system called D´Agent. We evaluated the system through an experiment and demonstrated its usefulness
