/sys$common/syshlp/helplib.hlb LINK, Qualifiers, /TRACEBACK  *Conan The Librarian (sorry for the slow response - running on an old VAX)

       /TRACEBACK (default)
       /NOTRACEBACK

    Directs the linker to include traceback information in the image
    file. If you specify the /DEBUG qualifier, the linker includes
    traceback information by default, overriding the /NOTRACEBACK
    qualifier if it is specified.
