+*dos.h - definitions for MS-DOS interface routines
+*
+*	Copyright (c) 1985-1993, Microsoft Corporation. All rights reserved.
+*
+*Purpose:
+*	Defines the structs and unions used for the direct DOS interface
+*	routines; includes macros to access the segment and offset
+*	values of far pointers, so that they may be used by the routines; and
+*	provides function prototypes for direct DOS interface functions.
