Leveraging Range Names in Excel Macros

EE Pros,
I will preface this as perhaps a strange question;
I often have a situation where I build a model that when I add a row or column, it screws up the Macro.  When I use range names rather than cell references in a macro, it generally works out much better.  With that said, how do quickly set up individual, non-contiguous cell references as range names (right now, this process is very laborious) and then now do I reference them in a Macro without listing each range name?
Thank you in advance,

Can you give an example of your code that causes problems when you add a row. I think it would be better to address this problem first.
I am not sure I understand your question "How do I reference them in a Macro without listing each range name" ?

You have to either use the name or iterate through the 'workbook,names' or 'worksheet.names' collections
Martin LissOlder than dirtCommented:
If the names of the named ranges that you want to use have something common, you can do the following. This example assumes that they start with "Test".
Sub x()
Dim NR As Name
Dim rng As Range

For Each NR In Names
    If Left$(NR.Name, 4) = "Test" Then
        If rng Is Nothing Then
            Set rng = Range(NR)
            Set rng = Union(rng, Range(NR))
        End If
    End If

' do something with rng
End Sub

So Martin, You still have to name all the ranges.....even if they are single cells, but you can reference them in the Macro as a "group"?   Even if they are non-contiguous?  Right?  Then, even if you move them around by say adding a column or row, they will auto adapt?

Roy, it's not a problem as much as it is in understanding how I may avoid one in the future.


Martin LissOlder than dirtCommented:
Yes to everything you asked except that the "move them around part".  My code deals only with using existing ranges.
Bright01Author Commented:
Right.  But even with your code, your code doesn't care WHERE the Ranges (i.e. cells) are in the WS.... and performs the operations on them because they are named and not specific addresses.

Do I have that right?

Martin LissOlder than dirtCommented:
That's correct.
