How can I dynamic give a name range address by R1C1 Format?

[Prectice]

If I get a name range address such as ：C3:C64 , transfer to R1C1 is R3C3:R64C3

Suppose I want to change 3 -> top_i
64 -> btm_i

How could I do for this case?

e.g.

XXX.XXX."R" & top_i & "C3:R" & btm_i & "C3".XXX <--- it seem not working anyhow ?

what do the xxx stand for

With Range("C3:C64").EntireColumn
    MsgBox Range(.Cells(Top_i, 1), .Cells(btm_i, 1)).Address(True, True, xlR1C1)
End With

    MsgBox Range(.Cells(Top_i, 1), .Cells(btm_i, 1)).Address(True, True, xlR1C1)
End With

The Code come from a macro.. about assign a name range ... I forgot the detail code , but only remember aside the R1C1 address , are have some code there.
and I " " & " " method , seem not working anyways.

This code document now not beside me . If needed , I will supplement XXX really stand for the other day.

Thanks you kind help again sincerely.
