Macro: Process The Cells For Every Worksheet In A Book Rather Than Just The Active One

I need to get this macro to process the cells for every worksheet in a book rather than just the active one


Public Sub test()
Dim Lr As Long, i As Long, x As Range, _
v1 As String, v2 As String, v3 As String
Set x = ActiveSheet.Cells.Find("*", searchdirection:=xlPrevious)
If x Is Nothing Then Exit Sub
Lr = x.Row
Application.ScreenUpdating = False
For i = Lr To 1 Step -1
v1 = Cells(i, 2)
v2 = Mid(Cells(i, 3), 1, 1)
v3 = Cells(i, 4)
If v1 "OP00" Or v2 "L" Or v3 "CC" Then Cells(i, 1).EntireRow.Delete
Next
Application.ScreenUpdating = True
End Sub
