 option

    The option REDUCE, which stores a library in data-reduced format,
    or the option EXPAND, which expands a library previously stored
    in data-reduced format. There is no default; you must specify one
    of the options.

     For I64 systems, VSI strongly recommends that DCX
     data-reduced ELF object libraries first be expanded
     before performing Linker operations.
