with Subscript or Index concept to access a record in a
sequential file.

Hi Guys,
when you say "sequential" it means you have to read from 1
to 9999...Never say sequential file and read randomly !!!!!
use read util the field you want....
Perform 100-read until ws-field = 'yes'.......

Answer / harish
YS WE CANT ACCESS FLAT FILE RANDOMLY
IF WE WANT TO ACCESS PARTICULAR RECORD
PROCEDURE DIVISION.
MOVE KEYFIELD VALUE TO W-S VARIABLE
PERFORN UNTIL W-FLAG = 'Y'
READ FILE1 AT END MOVE 'Y' TO W-FLAG
NOT AT END
IF KEY-FILE1 = WS-KEY-VARIABLE
MOVE--------
ELSE
MOVE 'Y' TO W-FLAG.
pls correct me if anything wrong
