COLUMN /LINES

        [GREG1\]COLUMN /LINES L1 [L2]

    limits the range of lines read in the input file or table. L1 and L2 re-
    fer to absolute line numbers. Since comment lines are ignored, number of
    read  lines is at most L2-L1+1, and can be 0 if all lines were comments.

    This option is useful to avoid non-data lines, or to read  by  pieces  a
    formatted  file  which is too long for the column buffers. L1 and L2 are
    reinitialized for each new input file or table. L2 defaults  to  end  of
    file if not specified.
