Module Name:

    globals.hxx

Abstract:

    This module, contains all global definitions and declarations needed by
    other modules, except those which depend on locator-related classes.
    The latter are in "var.hxx".

  Author:

    Satish Thatte (SatishT) 08/16/95  Created all the code below except where
                                      otherwise indicated.
