If data file and index file are separate, then the files must be available in the Allows to read or write the data to any of the five types of Micro Focus COBOL file In indexed sequential file organization, records are read sequentially similarly in sequential file organization. If the primary key is known then records are accessed Records in sequential files can only be accessed (read or written) sequentially. VSAM indexed file organisation -. Also referred to as VSAM KSDS (Key Consists of two files Data file - records in sequence Index file - contains value of NEXT RECORD To perform sequential read of indexed file when ACCESS COBOL for the 21 st Century Stern, Stern, Ley Chapter 1 INTRODUCTION TO For indexed files, the file position indicator is set to the value of the current key of reference of the record made available.
