;except.inc - definitions for exception handling
;
; Copyright (c) 1990-1991, Microsoft Corporation. All rights reserved.
;
;Purpose:
; Structure and constant definitions used by exception handling code.
;
;Revision History:
; 07-19-90 GJF Module created.
; 08-28-90 GJF Added some definitions of exceptions.
; 10-19-90 GJF Revised some constants to agree with the definitions in
; \\os2rel\public!2.0\h\bsexcpt.h (dated 10-1-90).
; 07-30-91 GJF Different values of _XCPT_CONTINUE_[SEARCH|EXECUTION]
; for Cruiser and Win32 [_WIN32_].
