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

       /SECTION_BINDING=(CODE,DATA)
       /NOSECTION_BINDING (default)

    For Alpha linking, directs the linker to create an image that can
    be installed as a resident image and to flag coding practices in
    the image that would prevent this.

    CODE prevents the linker from replacing the Jump to Subroutine
    (JSR) instruction sequence with the more efficient Branch to
    Subroutine (BSR) instruction sequence when the target of the
    branch crosses an image section boundary.

    DATA directs the linker to check for address calculations that
    create dependencies on the layout of data image sections. The
    linker reports such occurrences.

    When the /SECTION_BINDING qualifier is specified without either
    the CODE or DATA keyword, the linker performs both types of
    checking by default.
