+If you're scanning through a file using wxTextInputStream, you should check for EOF {\bf before}
+reading the next item (word / number), because otherwise the last item may get lost. 
+You should however be prepared to receive an empty item (empty string / zero number) at the
+end of file, especially on Windows systems. This is unavoidable because most (but not all) files end
+with whitespace (i.e. usually a newline).
