        The WATCHPOINT UTILITY is an Internal Use Only debugging tool that
        maintains a history of modification that are made to a particular
        location in system (S0) address space.  The WATCHPOINT  command
        interpreter (WP) issues $QIO request to the WATCHPOINT driver
        (WPDRIVER) from commands that follow the standard rules of DCL
        grammar.

        Commands may be entered at the WP> prompt to set, delete, and obtain
        information from watchpoints.

        Before invoking the WATCHPOINT command interpreter (WP), the
        WATCHPOINT driver (WPDRIVER), must first be installed with SYSGEN.
        This can be accomplished as follows:

        $ RUN SYS$SYSTEM:SYSGEN
        SYSGEN> CONNECT WPA0:/NOADAPTER
        SYSGEN> EXIT

        The WATCHPOINT command interpreter (WP) can then be invoked with the
        command:

        $ RUN SYS$SYSTEM:WP

        Commands may then be entered at the WP> prompt to set, delete,and
        obtain information from Watchpoints.
