I want to sum for multiple records, one member number.  How do I keep a member number while continuing to read the file?  
read in a record, assign member_nbr to HoldMember_Nbr
process that record
read in a new record, check if Member_Nbr = HoldMember_Nbr
If it does not process that record
If it does write record to a new file.

Dim Member_Nbr, CurrentMbrNbr, Share_Nbr, TransType, DAATMWCNT, DACUATMWCT, DAFCCNT, DAATMWCNT37, DACUATMWCT37, DAFCCNT27, DAFCCNT37 As Integer
        Dim TransDesc, NetOrg, TermID As String
        Member_Nbr = 0
        CurrentMbrNbr = 0
        Share_Nbr = 0
        TransType = 0
        TermID = ""
        TransDesc = ""
        NetOrg = ""
        DAATMWCNT = 0
        DACUATMWCT = 0
        DAFCCNT = 0
        DAATMWCNT37 = 0
        DACUATMWCT37 = 0
        DAFCCNT27 = 0
        DAFCCNT37 = 0

You store in a variable that will only change when you detect that the value on the variable is different than the value on the current record

Where in the code do you store the variable, the way I have it now it changes everytime you read a new record?  I am used to Access code and does this routine different than vb.net.  I have always used next record, but vb.net does not have (as far as I know) this function.
