/PATHNAME
       /NOPATHNAME

    Specifies to use full pathnames for each routine name in the
    plot. /NOPATHNAME specifies to use unqualified routine names.

    Note that /NOCHAIN_NAME and /NOPATHNAME are the default CALL_TREE
    domain qualifiers.
    Note that if you do not specify one qualifier from each category,
    a default qualifier is used. If your PLOT command has one or
    more node specifications, the qualifier defaults are taken from
    the SET PLOT defaults. If your PLOT command does not have a node
    specification, all qualifier and node specification defaults are
    taken from the last PLOT or TABULATE command you entered.
