//  ALArchiveBase::Delete()
//
// DESCRIPTION
//
// EX03PM.CPP demonstrates ALArchiveBase::Delete().  It lets you
// select a list of files to delete from an archive, then performs
// the deletion.  The list boxes are updated right afterwards so you
// can see the results.
//
// This is a very simple PM program.  It works by creating a modeless
// dialog box, then wrapping a framing window around it.  By using a framing
// window as the main window we are able to handle accelerator keys, menus,
// and icons a bit easier. Because of this approach, main() and
// MainDialogProc() are not very exciting, and have been moved down to the
// bottom of the file.  MainDialogProc() does handle menus and accelerator
// keys, so it comes first.
//
// REVISION HISTORY
//
//  February 1, 1996  2.0A  : Second release
