Hello and TIA for your help. I'm looking for the quickest
way to select every odd column of a worksheet in VBA.
Here are 2 methods I have, although the 1st one doesn't
select column IU.

1) My solution (not selecting col. IU - why?):

Sub test()
Dim i As Integer
Dim ws As Worksheet
Dim rng1 As Range
Dim rng2 As Range
Dim col As Range
Set ws = ActiveWorkbook.ActiveSheet
Set col = ws.Range("A:A")
For Each col In ws.Columns
If col.Column Mod 2 = 1 Then
If rng2 Is Nothing Then
Set rng2 = rng1
Else
Set rng2 = Union(rng2, rng1)
End If
Set rng1 = col
End If
Next
rng2.Select
End Sub

2) Macro Recorder:

Range("A:A,C:C,E:E,G:G,I:I,etc.,etc.").Select
