VSAM Key handling to read randomly.

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.
