          Logic:    DF  0             (Increment in string instructions)
 
    CLD zeros the Direction Flag. No other flags are affected. Clearing
    the direction flag causes string operations to increment SI and DI.

       Note:          String instructions increment SI and DI when the
                      direction flag is clear.
