JMode v1.00
by Jason Keeney

Introduction
------------
The MODE.COM program provided by OS/2 is a means to change the display mode
of a command line session. If you're like me, you spend a lot of time in
a command line session (despite the efforts of the slick Workplace Shell)
and welcome the ability to get more than the standard 80 columns and 25 rows.
One of the potentially more useful modes, because of it few extra lines and
readability on a 14" monitor, is the 80x30 mode (though I believe it's not
documented in OS/2's on-line help facility). However the 80x30 mode as
provided by MODE.COM is plagued by a hideously awkward font. Quite frankly,
it's down right ugly. This is because the vertical resolution of the
80x30 mode doesn't lend itself well to being divided by 30.
The good news is that the VGA is capable of expressing 80 columns by 30
rows in a number of different display resolutions. This is where JMode
comes in. By expressing the 80x30 text mode with a higher physical
resolution, JMode lets each character cell take on the same proportions
as in the standard 80x25 mode. This provides the extra lines of 80x30
with same readible font of 80x25.
Usage and requirments
---------------------
JMode's only real requirement is that you are running OS/2 and have a
display capable of 640x480 pixels. Note that this might exclude some
portable LCD displays and is probably the reason that IBM chose a lower
resolution for the 80x30 text mode.
To set your display to JMode's good looking 80x30 mode, place JMode.Exe in
a directory pointed at by your PATH setting and type
JMode
from a command prompt. Also, by adding
/k JMode
to the Parameters section in the Settings notebook of your OS/2 Full Screen
or OS/2 Window icons, it will automatically run JMode each time you begin
these sessions.
Though there is no real reason for it, this program is 32-bit and will
therefore only run on OS/2 versions 2.0 and above. This is only because
my compiler will not create a 16-bit executable.
Other information
-----------------
The zip file for JMode should contain all the following files:
JMode.exe - The JMode program
JMode.txt - This file
This program may be freely distributed as long as all this and all
accomanying files remain unaltered. In fact please pass this package on
to friends and upload it to your favorite bulletin boards, etc...
Though I do not require any kind of registration fee, I would ask that you
send me a postcard (or at least some e-mail) just to let me know you're
using my program. A donation of $1 to help defer the development costs of
this and any future releases would be a great encouragement and would also
put you on my "Preferred User" list. =)
Any correspondence should be sent to:

Questions, comments, suggestions for future versions, complaints, and bug
reports are all welcome.
Future Versions
---------------
If there is a response, I plan to increase the capabilities of JMode to
provide other potentially useful, non-standard modes. Again, your
suggestions are more than welcome.

Trademarks
----------
Any trademarks I've used like OS/2 or Workplace Shell, belong to whomever
owns them. Although I have used them without permission, I have tried
not to misuse them. I hope that out of the goodness in their hearts and
the fact that I have no money, that they do not sue me. =)
