Abstract
PURPOSE: To improve the productivity of the program such as a word processor, etc., by changing the elongation, shortening, etc., of the record of an successively organizing file only by correcting the data of the record in an application program.
CONSTITUTION: When the writing request of a variable length record of an successively organizing file is inputted and a second preparing means 4 inputs the discrimination result of the effect that a new variable length record is longer than a present variable length record in a record length from a comparing means 2, the new variable length record is written to the position different from the position to store the present variable length record on the memory medium and the writing position is written into the control information of the present variable length record on a memory medium. Thus, even when the record length of the new variable length record is elongated, it is not necessary to execute the re-writing processing of the whole of a program and the productivity of an application program to execute the data processing of the successively organizing file of a variable length record is improved.
