/sys$common/syshlp/helplib.hlb CMS, REPLACE, Command Parameters  *Conan The Librarian (sorry for the slow response - running on an old VAX)

 element-expression

    Specifies one or more reserved generations of an element to
    be replaced. An element expression can be an element name, a
    group name, a wildcard expression, or a list of these separated
    by commas. If you specify more than one element (with either a
    group name or a wildcard expression), each file indicated by the
    element expression must exist in the same directory. When you use
    wildcards, CMS creates an input element list based on the list of
    element generations that you have reserved.

 remark

    Specifies a character string to be associated with the newly
    created generations, to be logged in the history file with this
    command. The remark is enclosed in quotation marks. If no remark
    was entered, then the remark from the corresponding reservation is
    used for the new generation and the replacement transaction in the
    history file.
