Page 5 - TI 83+/84+ programming?

post code please

ok i wrote this barf program and i got some of my source from this site http://home.hccnet.nl/bram_s/ti-83/index.html it's under boggle and the program is really funny

that's cool man

ok if anybody has a program that they want better just ask here i'll help and still act as if you did it on your own cause you will have to understand my help to use it

Hi! I am trying to make a program for a TI-83 Plus calculator for work and it should be simple but we can not figure it out!!!

***We need to have the program say "enter sum" and enter "age" and then give us the answer to the equation for us to record down for our clients. We can have 2 different programs so if someone could help us with one we could figure out the other one!!

What we are trying to do:

make a program for entering in values into an equation to get the answer.

Female:
"sum of 4 skinfolds" = x
"age" = a

equation=0.29669(x)-0.00043(x squared)+0.02963(a)+1.4072

the above equation equals "% Body Fat"

Male:
"sum of 4 skinfolds" = x
"age" = a

equation=0.29228(x)-0.0005(x squared)+0.15845(a)-5.76377

the above equation equals "% Body Fat"

thanks to anyone who can help in advance!!!!

Let's see....




That ought to do it.

Thank you very much!!! You are a lifesaver!!!

One quick question though...for the "->" what did you use for the ">" because I went to the catalog and picked the greater than symbol and it says I have an error!!

Thanks!

the -> symbol means that you press the sto> button

whats skinfolds?

hey...im kinda new to programming on a TI calculator, but I do know a little bit about programming (C++, BlitzBASIC). I am trying to write a program that works with the start up app that asks for a PIN number whenever the calculator is turned on.

I have everything else put on there right but people can get around it using the 2nd Quit function, and they can also just hit enter and do the break error. Any way to disable them from doing this?

The source for the program is:

ClrHome
Disp " LOCK V0.1 BETA"
Disp " "
Lbl 1
Disp " ENTER PIN:"
Input Z
If Z=[pin number]
Stop
If Z≠[pin number]
Goto 1

I was thinking, if I could have it keep on using getkey and check if the 2nd button gets pressed it could just go back to Lbl 1...the only problem is that I can't get it to keep on checking it. I can get it to check it for a split second before it gets to the prompt loop, but thats it.

I have no clue how to get around the ERR:BREAK...in fact I dont think you can do it

o yea and about the programs that people have asked for in the past for things like distance forumula I have already made those that even show the work that was the first thing I worked on.

maybe you can do this:

Lbl2
Output(1,1,"PIN=")
0->X //Postion of key to be pressed (you'll see why this is needed)
Lbl 1
getKey->K
If K/=105 or K/=0 //if a key is pressed and its not Enter or zero, then it counts it
Then //as a pin key (you can customize this to make it only numbers)
K -> List1(X) //Stores the key pressed into a list
Output(1,5,"*") //outputs "*" to make it show something like PIN=****
X+1->X //Moves the spot over for the next pin digit, ex: *_ to **_
End
If K=105 //if the Enter key is pressed (confirming the pin is entered)
Then
If List1(X) = {25,34,26} //compares the key sequence pressed to the password
Stop //the pin for this is Up,Right,Down and exits if True
ClrHome //If False, goes to the beginning of the program or whatever to
goto 2 //start the password entering process again
End
goto 1 //Loops back to the beginning for next PIN Digit


hope that helped

Hi, if you need a program to check, than you should make it so that it gives you the formula using a string and then gives you the answer. thats what I did and the program isn't very long
