TIMER for TI89
by Aaron Sarna and William White

This is a pretty straight forward program that is basically a timer. There are
a few things that you need to know in order to use it effectively:

1. To set the timer: when you start the program, you will see 3 sets of 2 zeros
that look like this: 00:00:00. The first two will be flashing. Tese are the
hours. To add hours press the up arrow. Once you have added hours, you can
remove them by pressing the down arrow. The left and right arrows allow you
to switch between hours, minutes, and seconds. To set the minutes and seconds,
press te left or right arrows until the correct set of zeros and repeat the steps
you used to set the hours.

2. To start the timer, at any time in the set mode press [ENTER] and the timer
will start.

3. At any point during the operation of this program you can press [ESC] to
quit, so you wont have to press [ON] if you accidentally set it for 99 hours.

4. When time is up, the screen will flash "Time's Up" until you press any key.
Now press [ESC] until you get back to the home screen.

5. The final thing that you have to do for the program to work well is to adjust the
speed of the clock. To do this you need to run the program and set the timer to any
amount of time, the more time you set it for the better the adjustment will be. Run the
timer next to a clock with acurate speed and see if the program adds or loses seconds.
Once you have determined this, you need to go into the programs code. Use the instructions
in step 4 to get into the code and scroll down pretty far until you see the following code:

	:Lbl S
	:While A=/=22:S-.45->S

To make the timer faster, change the .45 to a higher number. The number should never be
higher than 1. To slow the timer down make the number smaller but never zero or lower.
Keep on testing it against the clock and you can make the number up to 12 decimals long.
If you find a number that is exact or close to it then email it to me at shoofy@rcn.com.
If you use my email to sign me up for any lists or spam I will personally hunt you down.

I think that's all you need to know. If you have any questions email me at shoofy@rcn.com.
By the way, if this screws up your calcuator it's not my fault because it's a basic program
which doesn't have the capabilities to mess up your calculator in any real way by itself.
Chances are that you have a different program that is messing it up.
