TIMER for TI83+/SE
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. It will run from MirageOS.

3. At any point during the operation of this program you can press [MODE] 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.
If you want to add sound to your timer, first of all you will need headphones
with a 2.5 mm jack. Many cell hones have one. Then you will need to edit the code
for the timer program. Once in the code, press F1 a lot of times until you get to
a set of lines that read (at the very end of the program) :

	:Lbl D
	:ClrHome
	:Output(4,7,"Time's Up!"
	:DelVar(A

Add a line at the end of the program and type in "Asm(cartman)" without the quotes.
Make sure the program "cartamn" is on your TI-83+ and isn't archived. Now press
[MODE] until you get back to the home screen. Run TIMER and it should say "Screw
you guys, I'm going home!!!" through the speakers/headphones when time runs out. Plug
in the speaker or headphones after the program is running. If the calc freezes, just
remove them.

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.

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.

If you have compatibility problems or if the sound program messes up email

lists or spam I will personally hunt you down.
