ASPでは、.NETのStringオブジェクトと同様に、文字部分に対してPadLeftとPadRightの関数が実装されています。

Function PadLeft(Value,Length,sChar)
  Dim strText,I
  strText = String(Length,sChar)
  strText = strText & Value
  LeftPad = Right(strText,Length)
End Function

Function PadRight(Value,Length,sChar)
  Dim strText,I
  strText = String(Length,sChar)
  strText = Value & strText
  LeftPad = Left(strText,Length)
End Function
