Abstract

PURPOSE:To improve the processing capacity of a whole job by registering the logic structure or the attribute of a file to be generated in a catalog file, and executing file generation processing to generate the file during file open time in the data write-in processing. CONSTITUTION:An application program executes the open processing 31 of the file in the write-in processing 2 as consisting the logic structure or the attribute of the file, set by a user, to be a parameter. On the an open request in the open processing 31, it is decided by a system whether the objective file exists on a disk device 6 or not, and if not, the file 8 is generated as conforming to the parameter of the open request set by the user, and the attribute, etc., of the file 8 is registered in the catalog file 7. After this file generation processing, the customary data write-in processing can be executed. Thus, the file generation is executed dynamically by only the application program, and it comes unnecessary to start a utility program for the file generation processing beforehand.
