/SHARED=[NO]ADDRESS_DATA
       /NOSHARED

    Installs the file as a shared known image and creates global
    sections for the image segments/sections that can be shared. An
    image installed shared is implicitly installed open.

    When you use the ADDRESS_DATA keyword with the /SHARED qualifier, P1
    space addresses are assigned for shareable images. With the assigned
    addresses, the Install utility can determine the content of address
    data when the image is installed rather than when it is activated,
    reducing CPU and I/O time. A global section is created to allow
    shared access to address data image segments/sections.
