Library /sys$common/syshlp/dbg$help.hlb DEBUG, EXAMINE, Qualifiers, /SYMBOLIC  *Conan The Librarian (sorry for the slow response - running on an old VAX)

       /SYMBOLIC (default)
       /NOSYMBOLIC

    Controls whether symbolization occurs. By default (/SYMBOLIC),
    the debugger symbolizes all addresses, if possible; that is, it
    converts numeric addresses into their symbolic representation.
    If you specify /NOSYMBOLIC, the debugger suppresses symbolization
    of entities you specify as absolute addresses. If you specify
    entities as variable names, symbolization still occurs. The
    /NOSYMBOLIC qualifier is useful if you are interested in
    identifying numeric addresses rather than their symbolic names
    (if symbolic names exist for those addresses). Using /NOSYMBOLIC
    may speed up command processing because the debugger does not
    need to convert numbers to names.
