title: how to extract 2 characters from a string
body: <p>am in a confusion of extracting sub string  fro a given string according to the following algorithm,</p>
  
  <p><strong>Algorithm</strong></p>
  
  <p>every input string is of the format: 3nm , 4gn , 77jk so on..(ie., a string followed by a number)
  now what i need is that extract the alphabet from the string..</p>
  
  <p><strong>example</strong></p>
  
  <p>input: 77nm
  output : nm</p>
  
  <p>my contribution:</p>
  
  <pre><code>Private Function getbyte(s As String, ByVal place As Integer) As String
     If place &lt; Len(s) Then
        place = place + 1
        getbyte = Mid(s, place, 1)
     Else
        getbyte = ""
     End If
  End Function
  </code></pre>
  
  <p>but it will not solve my problem as it returns number as well as digits </p>
