I need to act upon the test "USA" found in the first three chars of a
cell.
This is what I did, but I get a compile error..
So I did something wrong. How do I copare against specifc characters?
Even better, can I use regular expressions?

str = ActiveSheet.Cells(r, c)
check = substr(str, 1, 3)
If (check = "USA") Then
' do something
End If
