Interesting. I think we must have been working on it separately together.

But, what I came up with is simpler :-P

[code]
' Gambas module file

Public Sub Main()

   Dim Customers As New Collection[]

   Customers.Add(["id": "312", "name": "Mary K Jones", "balance": 350, "phone": "423-614-12"])
   Customers.Add(["id": "472", "name": "Jim Bo", "balance": 75.5, "phone": "0416-763-274"])
   Customers.Add(["id": "666", "name": "The Devil Incarnate Himself", "balance": 99.999, "phone": "0413-100-200"])
   Customers.Add(["id": "2", "name": "Bozo Dog", "balance": 1.23, "phone": "0413-627-123"])

   For Each cust As Collection In Customers
     Print Pad(cust["id"], 8); Pad(cust["name"], 35); Pad(cust["balance"], 10); cust["phone"]
   Next

End

Public Sub Pad(sStr As String, iWidth As Integer) As String

   Return sStr & Space(iWidth - Len(sStr))

End
[/code]

Maybe not as versatile though.
