image is run
• To place the entire executable image in P0 address space
• To produce and protect shareable images
• To create a system image
• To include traceback information in the image
• To search system default, shareable image default, and user-default libraries
to resolve references
For more information about using linker qualifiers, see the OpenVMS Linker
