   on a line as possible. This command is particularly useful for
   comments and ordinary prose, but is not normally used with program
   code.

Qualifiers

Additional information available:

/COMMENT_COLUMN

      /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.
