/sys$common/syshlp/helplib.hlb SCA, FIND, Qualifiers, /MODIFY  *Conan The Librarian (sorry for the slow response - running on an old VAX)

       /MODIFY[=query-name]
       /NOMODIFY (D)

    Indicates that an existing query is to be modified. By default,
    each FIND command creates a new query.

    The /MODIFY=query-name qualifier indicates that the specified
    query should be modified according to the specification of the
    FIND command. The specified query must already exist.

    By default, the /MODIFY qualifier specifies the current query.
