METHOD OF UTILIZING OF REQUIRED DATA TO APPLICATION PACKAGE OF OUTSIDE FROM PRESCRIBED PERIPHERAL DEVICE OF COMPUTER APPARATUS AND DATA EXCHANGE LOGIC

摘要

PURPOSE: To share data between sub-systems which are independently developed. CONSTITUTION: A computer device 130 having an external peripheral equipment contains an operating system 135 and an application package 150 inside. The external application package is synthesized with the computer device 130 by means of data exchange logic and a data file containing information making necessary data to be used is generated by off line. If necessary data is requested when the external application package is executed in the computer device 130, a first package is accessed. Information contained in data files 151-154 are used for generating a command for obtaining necessary data. When the result of a prescribed application function is to be outputted, a second package is accessed. The second package uses information contained in the data file for outputting the command for outputting the result.
