SelectSaver - save and restore selected file handle
Contents
Description
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.
