VSAM Key handling to read randomly.
Posted: Mon Jan 09, 2017 4:13 pm
Hi All,
I am new to the VSAM... So kindly help me...
I have a VSAM with key length of 121 like below.
01 VSAM-KEY-REC.
05 VSAM-KEY-DATA PIC X(120).
05 VSAM-KEY-FLAG PIC X(01).
I want to read only the record which has VSAM-KEY-FLAG as 'N'.
I tried like,
MOVE LOW-VALUES TO VSAM-KEY-DATA.
MOVE 'N' TO VSAM-KEY-FLAG.
READ VSAM-FILE
KEY IS VSAM-KEY-REC
END-READ.
But it's not working, i have record with 'N' in 121th position but i am getting 23 VSAM status. I don't know the remaining keys of vsam i know only the last byte that is 'N'. Please help to resolve this one.
Thanks in advance.
