/COMMENT_COLUMN=CONTEXT_DEPENDENT (D)
       /COMMENT_COLUMN=number

    Specifies that the comment column should be determined from the
    context. LSE uses the position of the commented segment in the
    first line of the selected range as the comment column.

    Number specifies an explicit column number in which to align the
    comments. LSE aligns all commented segments in the selected range
    with this column; all paragraphs within the range have the same
    comment column setting. Number must be an integer in the range of
    from 1 to 131; also, the value must be consistent with the lengths
    of the comment delimiters used within the range.

    For a text fill, LSE ignores this qualifier.
