 127 NEW: BEGIN SEQUENCE
--------------------------------------------------------------------------------

     BEGIN SEQUENCE has been enhanced with two added clauses that increase
     the ability to generate and handle runtime errors and exceptions:

     1. RECOVER USING:  The RECOVER [USING <idVar>] clause defines
        an error recovery mechanism within the SEQUENCE construct where
        control branches after a BREAK.

     2. BREAK:  The BREAK <exp> clause now allows a return value to
        be specified that can be captured by the RECOVER USING clause.
        This is generally an error object to be passed to the RECOVER
        <idVar> where it may be used to determine the nature of the
        error.
