RE: Access Key for a Sub File ?

Hi
        I hope this method will help u.
        Intialize RRN to 1 and Chain the Subfile using RRN in a loop by
incrementing the RRN by 1untill matching (Greater than or Equal to)
record for Vocher given in the Position field is found.
        If Matching record is found then Move the current RRN to
SFLRCDNBR field and EXFMT the Control Record.
