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

       /RESIDENT[=([NO]CODE,[NO]DATA)]

    On Alpha systems, causes image code sections or read-only
    data sections to be placed in the granularity hint regions and
    compresses other image sections, which remain located in process
    space. If you do not specify the /RESIDENT qualifier, neither
    code nor data is installed resident. If you specify the /RESIDENT
    qualifier without keyword arguments, code is installed resident,
    and data is not installed resident.

    The image must be linked using the /SECTION_BINDING=(CODE,DATA)
    qualifier. An image installed with resident code or data is
    implicitly installed header resident and shared.
