Ok, so I have been told that loading all records into an array is not smart!
However I need to add 2 extra dimensions to the array.
Can someone please fix?

Note Input file has about 8 million records and growing each month!

I need to add a portfolio which has 750 unqiue elements
I need to add a product which has 25 unique elements

Here is sample code:
Sub Button5_Click()

Dim strLine As String
Dim strAcc As String
Dim strBu As String
Dim strNP As String

Dim lngStatus As Long
Dim lngCnt As Long
Dim lngPremium As Long
Dim sPremium As Single

Dim intcounter As Integer
Dim NewArray(1200, 8)
Dim BuArray(10)

Dim blnFound As Boolean
Dim intUniqueItems As Integer: intUniqueItems = 0

Open "c:\movtin.pro" For Input As #1
Open "c:\movtout.txt" For Output As #2


Line Input #1, strLine 'header line

p = 2
Do Until EOF(1)
polval2 = polval1

Line Input #1, strLine

strAcc = Mid$(strLine, 33, 1)
strBu = Mid$(strLine, 3, 2)

lngStatus = CLng(Mid$(strLine, 97, 1))
lngCnt = 1
lngPremium = CLng(Mid$(strLine, 283, 9))
sPremium = CLng(Mid$(strLine, 266, 9))


For m = LBound(BuArray, 1) To UBound(BuArray, 1)
BuArray(m) = strBu
Next

n = 0
Select Case (BuArray(n))
Case (BuArray(n))

blnFound = False

For intcounter = LBound(NewArray, 1) To UBound(NewArray, 1)

NewArray(intcounter, 7) = NewArray(intcounter, 7) + sPremium
NewArray(intcounter, 8) = CLng(NewArray(intcounter, 8)) + 1
blnFound = True
End If
Next

If Not blnFound Then
intUniqueItems = intUniqueItems + 1
intAcc = strAcc
NewArray(intUniqueItems, 1) = strAcc

End Select
