// A set of classes to simulate exceptions in C++
//
//   Partially copied from Carlos Vidal s article in the C users  journal
//   September 1992, pp 19-28
//
//   Operations defined
//      Try {     }
//      Throw ( exception object )
//      ReThrow
//      Catch ( exception class ) {      }
//      CatchAll {      }
//      CatchAndThrow
//
//   All catch lists must end with a CatchAll or CatchAndThrow statement
//   but not both.
//
//   When exceptions are finally implemented replace Try, Throw(E), Rethrow,
//   Catch, CatchAll, CatchAndThrow by try, throw E, throw, catch,
//   catch(...), and {}.
//
//   All exception classes must be derived from BaseException, have no
//   non-static variables and must include the statement
//
//      static unsigned long Select;
//
//   Any constructor in one of these exception classes must include
//
//      Select = BaseException::Select;
//
//   For each exceptions class, EX_1, some .cpp file must include
//
//      unsigned long EX_1::Select;
