Library /sys$common/syshlp/dbg$help.hlb DEBUG, RERUN, Qualifiers, /ARGUMENTS  *Conan The Librarian (sorry for the slow response - running on an old VAX)

       /ARGUMENTS="arg-list"

    Specifies a list of arguments. If you specify a quoted string,
    you might have to add quotation marks because the debugger strips
    them when parsing the string. If you do not specify arguments,
    any arguments that were specified previously when running or
    rerunning that program are applied, by default.
