/PLACEHOLDER=placeholder-name

    Specifies the name of a defined placeholder that expands in place
    of the token. The token gets its description, topic string, and
    body from the defining placeholder.

    Note that the /PLACEHOLDER qualifier is mutually exclusive
    with the /DESCRIPTION and /TOPIC_STRING qualifiers and the END
    DEFINE command must not be used on the DEFINE TOKEN command when
    /PLACEHOLDER is specified. No token body is specified with the
    /PLACEHOLDER qualifier.
