/sys$common/syshlp/helplib.hlb CMS, REPLACE, Qualifiers, /INPUT[=file-specification]  *Conan The Librarian (sorry for the slow response - running on an old VAX)

    Specifies a file to be used as input for the replacement
    transaction. If you use the /INPUT qualifier but you do not supply
    a file specification, CMS searches your current default directory
    for a file with the same name as the element specified on the
    command line. When you specify /INPUT, CMS deletes the input file
    from the specified location after the new generation is created
    (unless you specify the /KEEP or /RESERVE qualifier).

    CMS must be able to match the input element list with the list of
    elements indicated by the element expression parameter. Thus, if
    you use wildcards in the /INPUT file specification to generate
    more than one input file, you must also use wildcards in the
    element expression parameter.
