  • Rational Developer for System z - RDz - v9.1.1.2
    
    Description :
    Several uses of "DUMMY" in PL/I sources displays an "Ambiguous
    reference" message.
    Here are the steps to reproduce :
    - Create a PL/I program with this structure :
    PLIPGM: PROC OPTIONS(MAIN,NOEXECOPS) REORDER;
    
    DCL 1 AAAAAA,
    3 AAAAAA UNAL       ,
       5 PARAMETER1      ,
         7 VAR1A                      CHAR (8),
         7 VAR2A                      CHAR (6),
         7 VAR3A                      CHAR (4),
    3 DUMMY CHAR(0);
    
    DCL 1 BBBBBB UNAL,
    3 BBBBBB ,
       5 VAR1B                        CHAR (2),
    3 DUMMY CHAR(0);
    
    DUMMY: PROC;
    END DUMMY;
    
    END PLIPGM;
    
    - On the END DUMMY line, the message "Ambiguous reference" is
    displayed.

    "Change to AAAAAA.DUMMY" and "Change to BBBBBB.DUMMY".
