I get this code to work for small lists, however, the
real test is on almost 54,000 records and the code
crashes when j = 32,767. In a nutshell Col B and Col C
have values and are being compared against Col F and Col
G (If B=F AND C=G, then H=1)

Dim i As Integer
Dim j As Integer

i = 1
j = 1

Do While Not (IsEmpty(Cells(i, 2)))
i = i + 1
Do While Not (IsEmpty(Cells(j, 6)))
j = j + 1
If ((Cells(i, 2) = Cells(j, 6)) And (Cells(i, 3)
= Cells(j, 7))) Then Cells(j, 8) = "1"
Loop
j = 1
Loop
