METHOD FOR ENABLING LOCATION-INDEPENDENT AND LOCATION-TRANSPARENT INTERACTION BETWEEN PROGRAM AND USER, DATA STRUCTURE, AND EXECUTION SHELL

摘要

PROBLEM TO BE SOLVED: To provide a system and a method for allowing information related to other presence locations to be inputted and outputted between a user and a program without constantly obtaining it. SOLUTION: This method allows a mobile user, or a user interacting with a mobile program to initialize a program status request at any time. The program status request initializes the sequence of events whereby the current location of the program is determined, and the current user location is made available without the necessity of knowing the changing location with respect to the program. Further, the agent script for the program maintains a composite data structure including: an input buffer for storing input variables; an output buffer for storing output values to be displayed to the user; a program state data structure; and a bag buffer for temporarily storing input variables which the program will need in the course of future execution. By maintaining such a composite data structure, it is assured that all necessary information can be provided at a program location regardless of whether the program or the user has relocated.
