/DEFINITIONS=n

    (Alpha only, Integrity servers when optimized code is supported)
    When the code is optimized, displays n definition points for a
    split-lifetime variable. A definition point is a location in
    the program where the variable could have received its value.
    By default, up to five definition points are displayed. If more
    than the given number of definitions (explicit or default) are
    available, then the number of additional definitions is reported
    as well. (For more information on split-lifetime variables, see
    the VSI OpenVMS Debugger Manual.

    The minimum abbreviation is /DEFI.
