PURPOSE:To ensure the effective application of the computer resources and the human resources by securing the similar forms to each other between the directory constitutions of a working system disk and a test system disk and designating a file based on the designation of a directory bus. CONSTITUTION:The similar forms are secured to each other between the directory constitutions of a working on-line system disk 22 and a test system disk 33. Then an on-line system is formed. In this case, an access is given to a file 22a through the relative designation of buses when the file 22a is started by a program 22b stored in the disk 22. In the same way, the disk 33 is started when a test system is formed and a program 33b stored in the disk 33 has an access to a file 33a based on the relative designation of buses. Thus it is possible to operate a working on-line system and a test system in parallel with each other. |
