/*
** Name: ex_handler - SXF exception handler.
**
** Description:
** This routine will catch all SXF exceptions. Any exception caught

** all future callers will be returned an error.
**
** Inputs:
** ex_args Exception arguments.
**
** Outputs:
** none
**
** Returns:
** EXDECLARE
**
** History:
** 9-july-1992 (markg)
** Initial creation.
** 12-jan-1993 (robf)
** Upgrade to new exception handling standard using ulx_exception()
** call.
** 10-mar-1993 (markg)
** Fixed typo in call to ulx_exception().
** 25-may-1993 (robf)
** New error message with appropriate params (fixes ule_format
** error on exceptions )
