VMS Help CMS, CREATE, ELEMENT, Qualifiers, /INPUT[=file-specification]  *Conan The Librarian (sorry for the slow response - running on an old VAX)

    Specifies the file to be used to create the element. When you
    specify an alternative location for the input file, CMS deletes
    the file from the alternative location (unless you specify /KEEP
    or /RESERVE). If you do not specify this qualifier, CMS searches
    your current default directory for a file with the same name as
    specified with the element expression parameter on the command
    line. Wildcards are allowed.

    CMS must be able to create a unique element for each file in the
    input file list. Thus, if you use wildcards in the /INPUT file
    specification to specify more than one input file, you must also
    use wildcards in the element-name parameter.
