Abstract

PURPOSE:To write another record into a deleted record to realize an effective use of the deleted record, by replacing the final record pointer when the final record is deleted for the data setting on a floppy. CONSTITUTION:When a deleting process is carried out with a floppy control method in which the write and deletion of record is carried out at random, the fact that the record is ineffective is displayed. At the same time, whether or not the deleted record is the final one is inspected. If the deleted record is final, the final record pointer which shows the final address of the data set to which the record written into the file level is replaced with an end address of the immediately preceding record. Thus another record can be written into the deleted record to realize an effective use of the deleted record.
