   Interesting discussion , thanks for the replies.   
   I have decided to provide students with a pre-defined function of my own   
   design   
   please review and improve if you can   
   the function:   
      
   Function isInteger(strVal As String) As Boolean   
      
    'if not numeric or decimal point found   
    If Not IsNumeric(strVal) Or InStr(strVal, ".") Then   
    isInteger = False   
    Else   
    isInteger = True   
    End If   
      
   End Function
