C2013   EXIT statement violates enclosing SEQUENCE

     Explanation:  You specified an EXIT statement between BEGIN SEQUENCE
     and RECOVER statements without an enclosing DO WHILE or FOR loop.  This
     could happen for several reasons:

     1. You specified an EXIT statement with no enclosing DO WHILE or FOR
        control structure within a SEQUENCE.

     2. You are attempting to EXIT from a DO WHILE or FOR control structure
        enclosing the current SEQUENCE from within the SEQUENCE.

     Action:  There are different ways of solving this problem:

     1. Check first to see if you omitted the DO WHILE or FOR control
        structure statements.  If so, add the control structure statements.

     2. determine if you intended to EXIT from a control structure enclosing
        the current SEQUENCE.  If so, you must BREAK to the RECOVER or the
        END statements and then EXIT.

     3. Remove the offending EXIT statement.
