Library /sys$common/syshlp/dbg$help.hlb DEBUG, RUN, 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
    quotes when parsing the string.
