In this code, note how the function always attempts to detect a bounds error. If it finds one, it
throws an instance of RWBoundsErr, a class that inherits from RWInternalErr. This instance
contains an internationalized message, discussed in
Chapter 16 ( Localizing Messages ) . The
RWTHROW macro is discussed in Chapter 19 ( Return Type of operator>>() ) .
Throwing an exception gives you the opportunity to catch and possibly recover the exception.
However, because the internal logic of the program has been compromised, most likely you will
want to attempt to save the document you are working on, and abort the program.
