VMS Help ANALYZE, /PROCESS_DUMP, Qualifiers, /RELOCATION  *Conan The Librarian (sorry for the slow response - running on an old VAX)

    On VAX systems, displays the addresses to which data structures saved
    in the dump are mapped in P0 space. (Examples of such data structures
    are the stacks.) The data structures in the dump must be mapped into P0
    space so that the debugger can use those data structures in P1 space.
