DESCRIPTION    [Toc]    [Back]

     A SelectSaver object contains a reference to the file handle that was
     selected when it was created.  If its new method gets an extra parameter,
     then that parameter is selected; otherwise, the selected file handle
     remains unchanged.

     When a SelectSaver	is destroyed, it re-selects the	file handle that was
     selected when it was created.
