Why would you want to do an Unchecked_Conversion.  See Ada.Text_IO, or 
Ada.Integer_Text_IO.  But if you have already read in a string you can 
use the attribute function Integer'Value(Some_String).  Note that the 
function will ignore leading and trailing spaces, but otherwise can 
raise an exception which may not be what you want.  See RM 3.5(52)
