       /SELECT
       /SELECT=(file-spec[,...])

    Input Save-Set Qualifier

    Selects the specified files for processing. If you specify more
    than one file, separate the file specifications with commas and
    enclose the list in parentheses.

    Do not use a device specification when you define the files to be
    selected. You can use most standard wildcard characters, but you
    cannot use wildcard characters denoting latest version of files
    (;)  and relative versions of files (;-n).

    You cannot use the /SELECT qualifier in image save operations.
