+*dos.h - definitions for MS-DOS interface routines
+*
+*   Copyright (c) 1985-1988, 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.
