Watchpoints are activated when you set them with the SET WATCH
    command. Use the DEACTIVATE WATCH command to deactivate one or
    more watchpoints.

    If you deactivate a watchpoint, the debugger ignores the
    watchpoint during program execution. To activate a deactivated
    watchpoint, use the ACTIVATE WATCH command. Activating and
    deactivating watchpoints enables you to run and rerun your
    program with or without watchpoints without having to cancel
    and then reset them.

    By default, the RERUN command saves the current state of all
    static watchpoints (activated or deactivated). The state of
    a particular nonstatic watchpoint might or might not be saved
    depending on the scope of the variable being watched relative to
    the main program unit (where execution restarts).

    To check if a watchpoint is deactivated, use the SHOW WATCH
    command.
