VMS Help SCA, EXTRACT, MODULE, Qualifiers, /LIBRARY  *Conan The Librarian (sorry for the slow response - running on an old VAX)

       /LIBRARY=library-spec

    Specifies the SCA static library from which to extract the module.
    This library must be one of the current SCA libraries (established
    by a SET LIBRARY command). If you do not specify this qualifier,
    then SCA tries to extract the module from the primary library (the
    first of the current SCA libraries).
