Critical Error Handler manipulation.

Header File.....TCXLdos.h

                IntT PAS _CerrSet(IffpCP fa);
                VOID PAS _CerrOut(NOARG);

                IntT PAS _CerrPop(NOARG);

Source File.....OPS\_CRITERR.ASM

Arguments.......fa -  Critical Error Handler Routine

Notes...........Under normal conditions, these routines should not be
                needed by users.  A default critical error handler
                 _DefCrit  is installed by TcxlInit() when your program
                begins.  This is a "bare-bones" error handler.

                If you want more detail provided, the library also contains
                an alternate critical error handler  _AltCrit  that
                provides more detail than you or your customers would ever
                want.

                To replace the current error handler with either _AltCrit()
                or one of your own design, use _CerrPush() with a pointer
                to your own handler.  When you are finished using your own
                handler just call _CerrPop().

                handlers,
