Grapher V1.0 Beta README File
-------------------------------------------------------

Thanks for downloading this program. This program was first
intended as an exercise for my pascal class, but I decided to
release it because I thought it's pretty cool. I don't think 
this program is useful or something, but for one who has
programmed for only about 6 months it was a lot of work (and
fun!) indeed.

Installation : Copy all files to one directory.

Using Grapher : You can just type a function and set Xmin, Ymin,
Xmax, Ymax values.

	For Log(x) : Type Log10(x). 10 is base number here
	You can also type Log3(X) or Log2.71828(x)
	For x to the Nth power : X ^ N
	For Cos, Sin, Tan : Cos(x), Sin(x), Tan(x)
	For +, -, x, / : +, -, *, /
	You cannot use - as your first letter. ie) f(x) = -x
	Instead, you must do it like f(x) = 0 - x.

Command Line Options

	/? : Display help message
	/VESA : Use Vesa driver (800x600)
	/VGA : Use VGA driver (640x480)
	The default option is VGA

Future plan

	I'm not even sure if I will be releasing the future
	versions of this program, but following features may
	be added in future versions.

	- support for "e" or 2.718281828...

	- graphs of multiple functions

	- graph of derivative - this feature was included in
	the alpha version, but removed since it looked very
	confusing

	- improving display/calculation of x-intercepts and
	y-intercepts. It worked pretty well with the alpha
	version, but doesn't work well after I enhanced function
	handling.

	- displaying coordinates.

	- Syntax checker (error handler) to prevent it from 
	crashing.

	- faster execution - this program runs Ok on my Pentium
	75 but I don't think it'll run well with slow machines.
	The ability to change speed/precision will also be
	included

	- UI enhancement - Giving it text-windows interface

	- ability to save/load functions and other options

	- Finally, Windows version!

	Caltech (YES! It's HARD) prior to graduation (after
	the junior year). I have been in American school for
	only about 2 years and finished ESL (English as a
	Second Language) course about an year ago. I'm planning
	to major in either physics or computer science. I got
	all A's (Yes!) except English(B!). Any info would be 
	appreciated. My e-mail address is dankang@nuri.net

	I haven't made my homepage yet, but it will at http://
