NAME
    LINES 0.1, switch to 80x25, 80x43, or 80x50 text mode in DOS.

SYNOPSIS
    lines <option>

DESCRIPTION
    LINES is a utility that switches to 80x25, 80x43, or 80x50 text
    mode. Even though the same thing can be done with
    "MODE CON LINES=", I did not write LINES in vain:

    1) At the speed of floppies, a 487-byte .COM starts running
       immediately after you press <ENTER>, but there's a
       noticeable delay for MODE.COM, which is about a dozen or
       two kilobytes (depending on which one you use).
    2) If the only reason you have MODE.COM on a boot diskette is
       to use 43 or 50-line mode, you could use LINES instead
       to save a couple dozen kilobytes.
    3) The MODE.COM included with MS-DOS 6.22 does not let you
       use the "CON LINES=" argument unless ANSI.SYS is loaded,
       but you may not want to load it to save memory.
    4) Programmers (including me) can read the source to
       learn/remember how to *properly* return from graphics mode
       to text mode. If the screen was 80x43 when the program was
       invoked, it should be restored to 80x43 when it exits, even
       though it takes a little more work. Hint: the byte at 40:84
       has the number of EGA text rows - 1.

SYSTEM REQUIREMENTS

BUGS
    Even though 80x43 is supported by the EGA, LINES requires VGA.
