/sys$common/syshlp/helplib.hlb CMS, MODIFY, ELEMENT, Qualifiers, /POSITION=n  *Conan The Librarian (sorry for the slow response - running on an old VAX)

    Establishes the position attribute; that is, the character
    position at which the note generated by the /NOTES qualifier is to
    begin on the line. A file that has a position attribute must have
    a notes attribute. Thus, the /POSITION qualifier can be used only
    if the element already has an established notes attribute, or the
    /NOTES qualifier is used on the same MODIFY ELEMENT command.

    The value n is required and must be an integer in the range 1 to
    511. If the length of the line is less than n, the note appears
    at position n. If the length of the line is greater than or equal
    to n, the note is placed at the next tab stop after the end of
    the line. (Tab stops are at position 9 and every 8 characters
    thereafter.)

    If you omit /POSITION, any current position attribute remains
    unchanged.
