/TRAILER[=keyword]
       /NOTRAILER
    Positional qualifier.
    Controls whether a file trailer page is printed at the end of
    a file. The trailer page displays the job entry number as well
    as information about the user submitting the job and the files
    being printed. If the /TRAILER qualifier is positioned between
    the PRINT command and the file specifications, it can take either
    of the following keywords:
    ALL     Prints a file trailer page after each file in the job.
    ONE     Prints a file trailer page after the last file in the
            job.
    If you want the /TRAILER qualifier to apply to individual files
    in a multifile job, place the qualifier directly after each file
    that you want to have a trailer page.
    Use the /[NO]TRAILER qualifier to override the
    /DEFAULT=[NO]TRAILER option that has been set for the output
    queue you are using. The /[NO]TRAILER qualifier does not override
    the /SEPARATE=[NO]TRAILER option set for the queue.
