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. The execution of the READ statement 21 Nov 2007 000420 OPEN INPUT AGENCY-FILE. 000430 OPEN I-O ACCOUNT-INDEXED- FILE. 000440 PERFORM READ-TRANSACTIONS UNTIL EOF
In indexed sequential file organization, records are read sequentially similarly in sequential file organization. If the primary key is known then records are accessed
COBOL Tutorial studay material - indexed organization is indexed record key is , alternative record key is file status random files open, read, close, write , GOTO 21 Mar 2017 The best way you can use Indexed file Read syntax in your project with less efforts. This is a way of writing good syntax in COBOL. This program, using dynamic access, updates the indexed file created in the CRTIND program. The input When the input record is read, the program determines if it is: 5722WDS V5R4M0 060210 LN IBM ILE COBOL CBLGUIDE/ UPDTIND Index File contains the primary key and its address in the data file. Following are the key attributes of sequential file organization −. Records can be read in KEY Clause used for only Indexed files concept. AT END and NOT AT END is used for Sequential files reading to verify the END OF the FILE reached or not. Each record is identified by a unique ordinal number both when it is written and when it is read back. Indexed.
