COEXISTENCE ENVIRONMENT STRUCTURING METHOD AND RECORDING MEDIUM WHERE COEXISTENCE ENVIRONMENT STRUCTURING PROGRAM IS RECORDED

摘要

PROBLEM TO BE SOLVED: To structure environment wherein multiple versions of the same program can coexist on one system by discriminatingly executing multiple program groups differing in version through the operation of an automatic switching object. ;SOLUTION: A version decision process 141 when called by start programs of respective versions A and B decides the versions of the calling sources and refers to a constitution list 130 to decide the versions of objects to be called. A corresponding version calling process part 142 calls the objects of the decided versions. Thus, a coexistence environment setup process part 120 replaces the constitution list 130 and automatic switching object 140 for original objects to discriminate the program groups of the different versions, thereby creating environment wherein respective program products can coexist.;COPYRIGHT: (C)2000,JPO
