Are you new to TiBD? If so, then welcome to the community! This is a guide on how to do some of the basic things here on the forums. Let's start with the basics. Since you're reading this thread, I am going to guess you have already made an account. If you haven't, you can click here to Create Account.
Rules
Be sure to read the rules and code of conduct! They can both be found here . Please read and adhere to both of them.
Changing your avatar
 Click on the My Account button at the top of the page.
 Navigate to the Settings tab
 Click the button next to "Avatar" which says "Change"
 Follow the prompts to upload an image to use as your avatar
Editing your "About Me" page
 Click on the My Account button at the top of the page.
 Navigate to the Settings tab
 On the left side of the screen, you will see a tab titled About me, click that
 Add any information you wish to share
Adding a signature
 Click on the My Account button at the top of the page.
 Navigate to the Settings tab
 On the left side of the screen, you will see a tab titled Forum signature, click that
 Add a signature that will appear under all your posts
Introducing yourself
 Click here to go to the Community Introductions forum
 Click on the "New Thread" button
 Tell us about yourself! Common responses include Where are you from? What are some of your hobbies? What programming languages do you know?
Making a Post
 Navigate around forums! Find a thread you want to reply to. I personally like to use the Recent Posts page.
 Make sure the thread isn't outdated. Threads more than two or three months old are likely inactive, and the user no longer cares about a response. We consider these dead threads, so please do not reply to them.
 To contribute to the original post click on the "New post" button
 To contribute to a specific reply or post, click on the "Reply" button under the post you want to respond to.
 Edit the title if you want, although this is optional
 Write your response
 Note: you can use Wiki Markup in your reply to format it. Wiki Markup codes are found here
 Also note the "Char" Box in the upper right corner of the screen. It contains the TIBasic characters that aren't readily accessed from the keyboard. It is meant to be a nice convenience for people who want to post code on the forum, allowing you to quickly copy and paste instead of having to hunt them down every time.
Making a Thread
 Navigate to the Discussion Forums. There should be a button for this on the sidebar.
 Decide which forum most relates to what you want to discuss.
 Near the top of the page, click on the "Create new thread" button
 Add a relevant title, and a summary. Note that the summary should not be the same as your post, but rather a short description
 Write your post. As with any other post, you can use Wiki Markups
Adding a program to the archives
 Navigate to the Program Archives. There should be a button for this on the sidebar.
 In the box at the top of the page, there is a link to Add a Program to the Archive.
 Enter a name for your program in the box, and then click "Create Program Page"
 Fill in as much information as possible.
 Add a download by clicking on the "Select File" Button. Most programs are in the form of .8xp .8xg .zip or .rar
 If you do not have a download for your program, put the source code into SRC.txt and upload that, a site moderator may be able to compile the program later.
 Hit "Save"
 Your program is now on the archives!
Adding a file to the forums or a thread
 On any thread, or in the screen for creating a thread, look for the "Forum Attachments" link near the top, or the "Files" button near the bottom
 Clicking on this link will bring up a list of files
 To add a file, click on the "Upload a file from your computer" button
 Browse your computer and select which files you want to upload
 Click on the "Upload" button and wait for a confirmation message
 To download your file, just click on the name of the file.
 To get the download link, right click on the name of the file, and then select "Copy Link Address"
 Note: you can attach these files using wiki markup. To show an image use [[image pagename/filename]]. To attach any file, use [[file pagename/filename]]
 To find the "pagename/filename" open the file list (see step 1). Right click on the title of the file you would like, and copy the link. Paste the link where "pagename/filename" goes. Remove the link except for the part after "local—files"
Sending a message
 If you have a question for a specific user, you can send them a private message.
 Simply click on their avatar, and then the "Write Private Message" button.
 Alternatively, you can click on "My account" then "Messages" and look for the "New Message" button.
 Please note though, that we encourage public discussion, and that most content should be posted in threads.
 Click Here to go right to the new message screen.
 To see if you have new messages, look at the top of the page near your name. If you see (1) after your name, it means you have one new message. Similarly, (2) is 2 messages, (3) is 3, etc.
Get involved
Getting involved is the best way to learn! Explore the site! There is a lot of information here on TIBD, and it was contributed by users like you. Discuss, program, work with others. You can help this community grow by being active and involved here on TIBD. Also, be helpful! Please try not to rely on the community to only help you. You should try and help others also. This means that you should also not rely on the community to create your code for you. Asking for a routine or optimization is okay, but we are not willing to write your whole program. This is a community that is here to help you learn, and the only way for you to learn is to do it yourself.

Good luck! This game has no current high score system, i am still working on that, but it still works perfectly fine. It is a very small program, so no harm in downloading it at all.

Enables a grid of colored lines on the graph screen.
GridLine [color#]
Press:
 2nd FORMAT to access the graph format menu.
 Use arrows and ENTER to select GridLine.
TI84+ CSE/CE
2 bytes
The GridLine command enables a grid of colored lines on the graph screen (you can disable it with the GridOff command). How fine or coarse the grid is depends on the Xscl and Yscl variables. Drawing the grid just involves plotting points all the horizontal and vertical lines that intersect points of the form (A×Xscl, B×Yscl) that are in the graphing window. The grid can be colored based on any color variable or value.
Advanced Uses
GridLine can be used to shade the entire screen if Yscl is small enough that the lines on the grid are one pixel apart:
:ΔY→Yscl
:GridLine RED
This is one of the shortest ways to shade the screen, although Shade( can be used for a (usually) even shorter way. However, using GridLine is also very slow: the fastest way involves the Horizontal or the Vertical commands in a For( loop.
You could also use GridLine to draw the playing grid for a Dots and Boxes game.
Related Commands
Enables a grid of colored dots on the graph screen
GridDot [color#]
Press:
 2nd FORMAT to access the graph format menu.
 Use arrows and ENTER to select GridDot.
TI84+ CSE/CE
2 bytes
The GridDot command enables a grid of dots on the graph screen (you can disable it with the GridOff command). How fine or coarse the grid is depends on the Xscl and Yscl variables. Drawing the grid just involves plotting points all the points of the form (A×Xscl, B×Yscl) that are in the graphing window. The grid can be any colored defined by a color variable or value.
:GridDot BLUE //creates a grid of blue dots
:GridDot 12 //creates a grid of black dots
Related Commands
Returns the string representation of the value of the input.
toString(value)
This command is found only in the Catalog. Press:
 2ND CATALOG to enter the catalog
 T to go to commands starting with T
 Scroll down to toString(.
TI84+ CE OS 5.2
2 bytes
The toString( command, given any value including real numbers, complex numbers, lists, or matrices, returns the string representation of the value of the input.
toString(1337 //returns "1337"
toString({1,2,3} //returns "{1,2,3}"
toString([[1,2][3,4]] //returns "[[1,2][3,4]]"
toString(√1 //returns imaginary number "i"
toString( has less limitations than the eval( command. It can handle lists, matrices, and complex numbers. Another difference from eval( is that toString( is affected by display mode changes like Fix.
toString( replaces the old numbertostring routine previously used prior to OS 5.2.
Error Conditions
 ERR:DATA TYPE is thrown when the input is a string.
 ERR:NONREAL ANSWERS is thrown when the input is a complex number and your calculator is in REAL mode.
 ERR:SYNTAX is thrown when trying to evaluate a command that doesn't return a value.

Example of Inputting Hex Code
There are all sorts of small assembly programs that you can create simply using the calculator's builtin assembly commands (specifically, AsmPrgm84C and AsmPrgmCE), along with the appropriate hexadecimal code. In order to run a program, you need to use the Asm( command, where Asm(prgmPROGNAME is the program that contains the hexadecimal code.
As a word of caution, when entering in the hexadecimal, you need to be very careful that you type it in exactly as you see it. If there is a single incorrect character, the calculator might crash and reset your RAM when you turn it on again. We have tested the hexadecimal codes to make sure they work, but it's up to you to enter them in correctly.

…that the TIBasic Developer has a complete TIBasic Starter Kit filled with important tutorials, guides, and tips for new TIBasic programmers?
This game is based roughly on games like Labyrinth of Touhou, however instead of 16 characters, you will be using two active characters who synergize well to fight bosses.
It is currently a TIBasic game which runs with xLib, and is in early development. Planned future updates include a boss tower, more characters, and hidden bosses.
Apr  14 —  Members can now discuss TIBasic on the #tibasicdev IRC channel on EFnet. 
Apr  10 —  After years of development by TIBD members, the TIBasic Starter Kit has been completed. 
Here are some review exercises to help you practice your optimization skills.
1. Write a program that, given a string in Ans containing letters AZ, will return a list with the alphabetic positions of those letters.
Example:
"AZ
AZ
prgmLETTONUM
Ans
{1,26}
2. Change this short program so it doesn't flicker and then optimize it as much as possible.

<< Summary  Table of Contents  Starter Kit Review >> 
In this chapter, you learned some optimization techniques to make your programs smaller and faster.
 The Output( command can be used to display multiple lines of text by taking advantage of text wrapping.
 The Text( command can automatically concatenate multiple arguments into one output
 Storing large data used in multiple locations can save space.
 Using implied multiplication and factoring out like terms in expressions can save space and time.
 Understanding logical operators can help you eliminate extra parentheses to save space.
<< Graph Screen  Table of Contents  Exercises >> 
Returns the arc length of expression1 from start to end with respect to variable var.
arcLen(expression1,var,start,end)
Menu Location
Describe how to get the command from a menu.
This command works on all calculators.
X byte(s)
The arcLen() command uses the integral arc length formula to calculate the arc length of a function over the specified interval.
arcLen(cos(x),x,0,π)
3.82019...
Advanced Uses
The arcLen() command also works on lists of expressions:
arcLen({sin(x),cos(x)},x,0,π)
{3.820... 3.810...}
Separate unrelated advanced uses with a horizontal bar.
Optimization
This section includes both ways to optimize use of the command, and other common pieces of code that this command can replace in an optimization. Make sure to mention if the optimization improves speed of the program, size, or both. Sample code should be included too, preferably in the following format:
:∫(√(1+d(f(x),x)²),x,a,b)
can be
:arcLen(f(x),x,a,b)

<< Math Review Exercises  Table of Contents  What is Optimization >> 
A thorough understanding of math commands is essential to the mastery of TIBasic. It is strongly recommended that you practice using these commands in different situations so that you will know which ones to apply when necessary.
Commands Introduced
<< Complex Numbers  Table of Contents  Exercises >> 
Mode command that puts the calculator into Classic mode.
MATHPRINT
Press:
 MODE
 DOWN until you reach Mathprint or Classic
 ENTER on Mathprint
Alternatively, use the catalog.
TI84 2.53MP or later
2 bytes
MATHPRINT will put the calculator into Mathprint mode as opposed to Classic mode. In MathPrint mode, enhanced homescreen input formatting is available. The Classic mode will make the calculator display everything as a calculator of lower OS would, including input. For instance, rather than superscripting exponents as Mathprint mode would, Classic mode uses the simple caret syntax (^).
Mathprint mode:
2^{4}
16
Classic mode:
2^4
16
When in Mathprint mode, text and numbers are displayed much slower than classic on the home screen and the function menus load slower. This can be inconvenient in games that use the home screen, but can also make solving equations that involve fractions and exponents easier as the numbers are in their correct positions and are the appropriate size.

TI84+ CE OS 5.2 or higher
2 bytes
The Wait command was introduced in TIOS 5.2 for the TI84+CE. The Wait command tells the calculator to wait for a specified number of seconds before continuing. The specified amount of seconds can be a decimal, as it is not limited to whole numbers. This command can be useful for displaying information momentarily before proceeding in a program. The Wait command functions similarly to the Pause command, but without the extra arguments.
:Disp "WAIT FOR IT!
:Wait 4
:Disp "Surprise
Advanced Uses
The Wait command is useful for facilitating automatic linking within programs. Since the Get( and GetCalc( commands only work when the sending calculator is in a preemptible state, including a small Wait delay will allow the other calculator to receive data.
Because the Wait command is relatively new, it may be advisable to avoid using it to ensure compatibility with older operating systems. Similar functionality can be achieved with the second optional argument to the Pause command.
Optimization
Traditionally it was recommended to use either a For( loop or the rand( command to create a delay within a program. The For( loop takes more space, and the rand( command uses more memory during execution.
:rand(100
can be
:Wait 1
Error Conditions
 ERROR: INVALID is thrown if the Wait command is executed on the home screen.
Related Commands
Please see the AsmPrgm page. The functionality and use is the same between both commands. However, the Asm84CEPrgm is only available on the TI84+CE calculator. Keep in mind that hexadecimal for the monochrome calculators may not work on color calculators.

summary: 'A basic Connect 4 game for local multiplayer. Compatible with MirageOS.'
description: "This program features a very basic Connect 4 game. The idea and interface were taken from a program made by CodeMaster123 that you can check out at http://tibasicdev.wikidot.com/forum/t1441297/connect4. I looked at his program and rewrote it from scratch to improve it whilst keeping his design, so feel free to download his too.\n\nFor those of you who don't know Connect 4, it's very easy. A typical Connect 4 game has two players: one who has a bunch of yellow (light) coins and one who has red (dark) coins. The board, which is an upright standing grid of slots, each slot the size to hold one coin, has walls between each of said grid's columns to seperate them from each other, meaning that when one drops a coin in a column, that coin will go all the way down to the first available slot in the same column. Every slot has a hole smaller than a coin on both sides, meaning that the two players can see what colour the coin inside that slot has. The players take turns on dropping their coins in the grid. The goal of the game is to get 4 coins of your colour in one line without being seperated by one of the other player's coins: this line can be horizontal, vertical or diagonal.\n\nThat said, these are the controls for this digital version of said game: You control the cursor (your \"hand\") with the left and right arrow keys and drop the coin in the designated column using Enter. Every time somebody drops a coin, the program will calculate whether or not 4 coins of the same colour were connected. This calculation takes approximately two seconds. After that, the playernumber in the bottom right will change, signifying that it's the other player's turn. Since this game is local multiplayer, you hand the calculator you're playing on to the opponent, so they can drop their coin. Then they pass it back to you, etc…\n\nPlayer 1's coins are light, player 2's coins are dark. The first to connect 4 of their coins, wins. Have fun!"

Mancala is an ancient game in which player take turns dropping stones (or seeds) into holes (or houses) that form a 6x2 grid with an extra house on either end, which are the players' end houses. Player choose a house on their side of the grid, pick up the stones in that house and distribute them in the consecutive houses going in a counterclockwise manner. There are many rule sets to mancala, just as there were many civilisations that played versions of it. This page gives two versions: The "kahla" rule set widely used in the United States and coded by user kg583, and another rule set coded by TIGBR (rules are explained).
Version 1: Kahla
— Programmed by kg583 and optimised by the TIBasic Developer community (see credits for details)
— Compatible on both grayscale and color calculators
Version 1 rules:

Version 2:
— Programmed by TIGBR and optimised by the TIBasic Developer community (see credits for details)
Version 2 rules:
board 6 by 2 active houses with 4 stones starting in each, and two wells, one at either end.
Picture at start(Its been stretched a little)
Each player, on their turn, chooses a house on their side of the board. (6 options)
the stones from that house get distributed by picking them up, and placing 1 stone in each house consecutive to the last, going around in a counterclockwise pattern until the stones run out. If the last stone falls in one of the wells, then the player gets another turn. The first player to clear their side of the board of stones wins.
Player 1 goes again.
Now its player 2's turn.
End of game image:
Player 2 has won.

This was a COMMUNITY PROJECT and was developed in the Projects page
THANK YOU to everyone who participated in this community project!
If anyone experiences problems with the code on this page, please post on the "Discuss" page for this page. See the tools below.
It seems that we are ready to make a mancala page. once it is made, feel free to edit it to relative perfection. Both games will be published, And credit given to those who worked on this community project. THANK YOU to all those who participated. we are starting a new ABSTRACT STRATEGY BOARD GAMES project featuring Isola. Please come participate in this continuation of this page, if you want to.
ISOLA
This is a continuation of Abstract strategy board games in which we programmed Mancala.
the same rules apply to this community project
" In publication on the games page, credit will be given to the original contributor(s) of the code, and to those who helped optimise it. If there are many small optimisations, credits for the optimisations will be given to the TiCommunity, with a link to this page for clarification."
This project is dedicated to Isola, since Pedro, a guest, posted his code for Isola on the first Abstract strategy board games.
Here I will put the code that Pedro posted:

This is a repost of the code, because it is more organised to have a separate project for Isola.
Here is the page describing Isola: Isola (isolation)
Lets see what we can do to optimise this!
Link to the original Posts: Here
We have optimised the two games to a good point. They both work. the next step is to publish them on a new page titled "Mancala" under the games page.
Symbolic Division is a method of finding the roots and factors of a polynomial given at least one factor.
This is a function, rather than a program, and can be used in graphs, other functions, and programs.
Rather than returning a list of factors as a result, we return an expression.
Code
:synthdiv(colist,ftr)
:Func
:Local count,ansList,xexp,ansExp
:expr("x")→xexp
:0→ansExp
:newList(dim(colist))→ansList
:colist[1]→ansList[1]
:For count,2,dim(ansList)
:colist[count]+ansList[count1]*ftr→ansList[count]
:EndFor
:For count,1,dim(ansList)
:ansExp+ansList[count]*xexp^(dim(ansList)count1)→ansExp
:EndFor
:ansExpansList[dim(ansList)]/xexp+ansList[dim(ansList)]/(xexpftr)→ansExp
:Return ansExp
:EndFunc
What's Going On?
First, this is a function, not a program! To make a function, press F1 in the program editor, choose "3:New", and make sure the "Type:" is "Function"
This takes 2 arguments, a list, and a number. We assume that's what we are given, and don't bother to check the type of the arguments.
The first argument, colist, should be a list of all the coefficients in your expression. The second, ftr, is one single factor or root of your expression.
Variables
We then set up a few variables for our function.
Functions can read global variables, but cannot write or create global variables!
count is used in our For loops.
ansList is a list of all the factors we want to return
xexp is the expression "x". We use it to create the returned expression.
ansExp is the factors in expression form.
To prevent errors when making our expression, we set our answer expression ansExp to zero.
We create the answer list using newList() with the number of elements in our given colist
In symbolic division, you "drop" your first coefficient. We just store the first element of colist as the first element of our answer list ansList
Dividing
Now we start a For loop. We start from 2 since we already found our first answer above.
The next line multiplies the previous answer by the factor, and adds that to the current coefficient, storing it in the next element of our answer list.
Prettifying the Answer
We start another For loop.
Then we add our current expression to the answer list element times "x" to the power of the appropriate power. and store that as our answer expression.
Fixing an Error
After we prettify the answer, we have a mistake. Since the answer is an expression, we can easily subtract the mistake, and add our correction.
Returning the Answer
All Functions must return something using Return
Examples
Here are a few examples of use.

So, We have decided to work on Mancala first.
Since there are so many rules to this game, we are developing two mancala games. Both need to be optimised for size and speed though! If you are good at optimisation, please come help us. Also, If you are interested in Helping us program a different board game please post about it, and we can move on to that one after mancala is finished. As far as I can tell, we only have a few participants in this project at the moment.
This is your Basic connect 4 game. Drop Checkers down any of the 7 columns, taking turns until either the board is filled of one player gets four in a row. Try to understand the code. It uses Matrix [A] to track the game board, Var P as one or two to track whose turn it is, V as the inputed column, L2 as the height of the columns, And Z as the counter for the possible number of turns.

This Game was coded by TIGBR and optimized by jonbush and earthnite.
See development page
Our games page is already quite long, but it could be better. Lets program some board games
For anyone who is interested, there are several games that could be programmed. We would need to do them one at a time, posting code, optimising it, changing it, and then publishing it on the games page. here are some examples
1. peg solitare
2. Go
3. Isola (Isolation)
4. Mancala
… there are many possible others. If you're interested in participating in this community project, please post about your interest and which game you'd like to start on first, so we can get started. In publication on the games page, credit will be given to the original contributor(s) of the code, and to those who helped optimise it. If there are many small optimisations, credits for the optimisations will be given to the TiCommunity, with a link to this page for clarification.
This is useful for factoring large nth degree polynomials (and finding their roots, of course), as well as finding an upper and lower limit for the roots of an nth degree polynomial, as per the remainder and factor theorems and some others.
It uses L₁ for input of the coefficients of the starting polynomial, uses X for r in (xr) (what you're dividing by), so have those variables predefined (or put :Input L₁:Input X at the the beginning of the program), and it outputs L₂ as the answer with the last list entry as the remainder.
L₁  the coefficients of the polynomial you want divide by (xr)
L₂  the coefficients of the answer and the remainder is stored as the last list entry

Synthetic division works for problems in the following format.
(a_{0}x^{n} + a_{1}x^{n1} + a_{2}x^{n2} + … + a_{n1}x^{1} + a_{n}x^{0}) / (xr)
Where a_{0}≠0
For example,
Problem: find the roots of x^{3}x^{2}2x12=0
First we need to find all possible (r) in (xr)
Factor a_{n}:12 {±1,±2,±3,±4,±6,±12
Factor a_{0}:1 {±1
List of a_{n}/a_{0}:{±1,±2,±3,±4,±6,±12
this last list is the list of all possible r in (xr)
Now for synthetic division.

Input L1 with the polynomial's coefficients, {1,1,2,12→L1
Input R for r in (xr), 3→R
We get a L2 as an answer, the last entry in the list is the remainder, if this is 0, we know that (xr) is a factor.The other entries in the list represent the coefficients of the quotient, a polynomial of 1 degree less than the starting polynomial.
so for starting polynomial f(x) divided by (xr) , f(x)= (xr) * q(x) +R, where q(x) is the quotient of 1 degree less than f(x) and R is the remainder. if R is =0 (xr) is a factor of f(x) and f(x) can be broken down into q(x)*(xr)
Now, remember we found all possible r's? Well, do synthetic division for each of those r's until the remainder (R, the last entry on L2) is 0. when you have that, you rewrite your equation, so in our problem 3 for r gives 0 for R so we would rewrite the problem, using the coefficients as:
Input: {1,1,2,12→L1
Input: 3→R
Output {1,2,4,0
This means that (x^{3}x^{2}2x12) / (x3) = x^{2}+2x+4
(x3) is a factor of (x^{3}x^{2}2x12
Then use the quadratic formula with x^{2}+2x+4 to find the other factors.

description: "NOTE: IT IS RECOMMENDED TO READ ALL OF THIS INFORMATION THROUGH BEFORE PLAYING THE GAME, AS IT WILL BE EASIER TO UNDERSTAND HOW EVERYTHING WORKS.\n\nHello there! My name is Mew, and may I firstly thank you for visiting my game's page! A lot of hard work has been put into the game, and I'm glad people appreciate that! Now, let me give you some info on it:\n\nTHE CONCEPT:\n\nBased on the ancient reallife puzzle, you start out with 3 pegs, the first one having a chosen amount of layers stacked decreasing in size on it. Your job is to move that stack, in the same order, from the first peg onto the last one, obviously following the rules.\n\n\nTHE RULES:\n\nThese are the rules you have to follow while solving the puzzle. Obviously it isn't possible to not do that anyway, since I programmed them in.\nI also included a shortened version of the rules (along with the controls) in the game itself, so that when somebody needs them but doesn't have access to this page, at least they have that.\n\n1. Thou shalt not move more than 1 layer at a time. This is pretty obvious, because otherwise you would be able to just move the whole stack at once.\n\n2. Thou shalt not move nonatop layers. Together with rule 1 this means that you can only move a layer if it is the upmost layer on its stack.\n\n3. Thou shalt not put big layers on small ones. This rule makes it so that at any given moment in time, there are no layers forming an upside down cone shape in the game.\n\n\nCONTROLS:\n\nWhile in the menus, you navigate using the arrow keys and the Enter key. While in the game itself, you use the left and right arrow keys to move your cursor, the up arrow key to lift a layer and the down arrow key to drop it. At any time in a game, you can restart by pressing 2nd, or Alpha to return to the main menu. \nAlso, so that you don't forget what peg you are taking from/adding to (due to e.g. distraction), there are arrows designating your choice of movement.\n\n\nFAQ\n\nQ: Why is there no leaderboard for highscores?\nA: There are 3 reasons for this: 1. I ran out of space on the menu screens, so I would have to redesign the whole menu system (which I'm not going to do) just to add a single extra option, 2. Because it would mean that for every number of layers I would need to have a leaderboard for time and amount of moves, meaning I would need 8 different leaderboards. I can't imagine how much extra navigatingcode would have to be put into that… Finally reason 3: as I said already, I would need 8 different leaderboards, which obviously need to be stored somewhere outside of the program. I don't want to infest people's calculators with extra memoryconsuming parts, which they may not know are taking memory. I don't want anyone thinking they have just the right amount of memory to use my program, but eventually get an out of memory message. I've had it happen before, it's not cool. So why are there time and move counters then? Well, you could use it just for personal measure, but if you really wanted to compete with friends (assuming you have them) you could always make a leaderboard yourselves.\n\nQ: Why is there a sentence on my homescreen when I quit, what does it mean and how do I get rid of it?\nA: The reason it is there is because it's my signature. Every program I write in TIBasic I give a fitting phrase when it gets stopped. You can delete it like you delete your history, put your cursor on it and press delete. \nAs far as the meaning is concerned, it's a reference to the legend about the temple of Hanoi, where the priests guarding the temple have the same game (but in real life), which uttilises 64 golden rings. When the priests complete that puzzle (following the same rules as you have to in this game), it is said that that will be the end of the universe, or at least of humanity*.\n\nQ: Did you implement easter eggs?\nA: Maybe… It TOTALLY does not involve a secret code starting with K that rhymes with \"thee\" that has to be typed on the main menu using the arrow keys, 2nd, Alpha and Enter…\n\nQ: I can't use any of the options, is that a bug?\nA: Nope. To use an option, you first have to select it by pressing Enter, which will lock the cursor. Then, you can customize your options.\n\nQ: What do I do if I accidentally choose a wrong peg to take from/add to?\nA: Since there isn't an undo button for your last action, I would suggest selecting that same peg in the other direction: this makes the layer stay put, although it does add +1 to your move count.\n\nQ: Why does lifting a layer up and dropping it on the same peg count as a move?\nA: Because if you were to pick up a layer in real life and then put it on the same peg again, it would rather be seen as doing something as opposed to nothing.\n\nQ: I found a bug! What do I do?\nA: Post it below! I'd love it if others would like to help me improve my game by notifying me of bugs! After all, I'm only one person, and there might be flaws I didn't notice that others have.\n\nQ: What do I do if I have a question that's not listed in the FAQ?\nA: Like with the bugs, don't hesitate to post them below! I'll try to reply to everyone as well as I can.\n\n\n*This might not be such a crazy idea if you think about it. The minimum amount of moves required to solve the puzzle is 2^n1, where n is the amount of layers in the puzzle. This means that for the puzzle the legend is talking about, that would be 2^641~1,844674407e19 moves! So, let's say hypothetically that from start to finish there's not a single interruption, every move is the right move to eventually finish with the minimal amount of moves possible, and let's say a move takes at least 2 seconds to complete. That means it would roughly take 1.169.884.835.000 years to complete! Technically, we can't really predict that far into the future, but the chances of that being \"the end\" are definitely not unexisting…"

There are only 4 borders to choose from, so using the default colors will not work. Instead, you may only use a value between 14.
For example, to change the border color to light blue, do:
BorderColor 3
Here are the color values:
Color  Value 

Light Gray  1 
Snowy Mint / Light Madang  2 
Light Blue  3 
White  4 
The colors of borders 2 and 3 are not usable or accessible in any way except as a border color. The use of border colors 1 or 4 along with the appropriate background can create the illusion of a larger graph screen. However, nothing can be draw outside the standard window.

Notice, you must use the number of the function, rather than the entire function name, which would be Y_{3}.
As you may know, you can also use the value of the color, which can be any integer between 10 and 24. So, our last command could also be:
GraphColor(3,17

When On is selected, the calculator will detect asymptotes, adjusting the graph accordingly. This method of graphing is the most accurate, but is also much slower than graphing with asymptotes turned off.
An asymptote is, by definition, "a line that continually approaches a given curve but does not meet it at any finite distance." Basically, an asymptote is the line where a function does not have any values on a certain axis.

When Off is selected, the calculator will not detect asymptotes, adjusting the graph accordingly. This method of graphing is much faster than with asymptotes turned on. However, the graph can be erroneous when dealing with rational functions, as it will often draw extra lines to connect points near undefined values.

Let's review the commands you have learned concerning mathematical operations. Highlight the area next to the word Answer to reveal the answer. If there are certain topics you don't feel confident in yet, don't worry. Just go back to the appropriate page and review.
1. True or False: Subtraction is the same as adding a negative number.
Answer: True. 5  2 = 5 + 2
2. Which of the following expressions are equivalent?
 abs(5)
 30 / 6
 int(5.5)
 5^{1}
 30 / 5
Answer: Choices 1 and 4, which both equal 5.
3. True or False: The complex number i squared is equal to one.
Answer: False. i^{2} = 1
4. Evaluate the following expression. Remember the Order of Operations.
(1)Answer: The answer is 10. Remember PEMDAS
5. Which of the following commands will calculate the number of possible 3digit number lock codes? The code can use the numbers 0  30 and order does matter.
 3 nPr 30
 30 nCr 3
 3 nCr 31
 31 nPr 3
Answer: Choice 4. Order matters, making the code a permutation. The length of the code, or r, is 3 digits, and the number of possible digits. or n, is 31, because we can use all numbers from 1 to 30 as well as 0.
6. True or False: The default base of log(n) is 10.
Answer: True. To get a different base, use the logBASE function or the formula: log(x)/log(b) = log_{b}(x)
7. Which of the following trigonometric identities is correct?
 cos(x)  sin(x) = tan(x)
 tan(x) + cos(x) = sin(x)
 sin(x) / cos(x) = tan(x)
 sin(x) * tan(x) = cos(x)
Answer: Choice 3.
8. The max() command can be used as a spacesaving substitute for which kind of logical operator?
Answer: The operator OR. The min() command can be used as a substitute for AND statements.

Rounding  lirtosiast, Trenly
The int( command always rounds towards ∞, and iPart( rounds towards 0. Here are the other two directions:
int(X //rounds towards +∞
iPart(X+not(not(fPart(X //rounds away from 0
For natural rounding, where a number rounds up if the decimal part is greater than one half and down otherwise, use this:
iPart(X+(fPart(X)≥.5
To round towards the nearest N or multiple of N, the code would be:
X/N>X
NiPart(X+(fPart(X)≥.5

They are harder to type and can make code look confusing, so it is better to write your program using normal variables, and then switch to the faster ones when you're done. Do NOT use C/Y if you are using P/Y, because if you set the value of P/Y, the calculator changes C/Y to the same number. Also do not use any of the X or Y window variables, because that will alter the graph screen.
Use n, window variables, or finance variables when speed is important, because they take about 8000 fewer CPU cycles to access or store to, or about 0.5 ms on a TI84 series calculator and 1.3 ms on a TI83 or 83+. After thousands of times accessing the variable, the time can add up.

With our string stored in Str1, we loop through each character in order.
To convert to lowercase, we search for the uppercase characters in Str2.
To convert to uppercase, we search for the lowercase characters in Str2.
If it finds the other case character, we replace that character with the other case character. Otherwise, we skip the code to replace.
Example use:
"helLO wOrld"

"hello world"
"H^:'[]{}/ello* world"

1+sum(not(cumSum(L1=X)))
//Finds last occurence of X in L1
max((L1=X)cumSum(1 or L1))
Given a value in X, this code will search L1 and return the index number of the first (or last) occurrence of X.
For example, in a list L1={1,2,5,4}, the index value of the element 5 is 3. Storing 5 to X and running this code will return 3.
Error Conditions
The first routine returns 1+dim(L₁) if L1 does not contain X, so if L1={1,2,5,4} and one searches for 9, the code will return 5.
The second routine returns 0 if L1 does not contain X, so L1={1,2,5,4} and one searches for 9, the code will return 0.

With the introduction of color and a higher resolution screen than the monochrome calculators, the TI84+CSE and TI84+CE included the ability to display a background image on the graphscreen. The images variables are similar to the picture variables in that there 10 slots. In addition, functions can be drawn on top of images.
BackgroundOn recalls an image variable or color and displays it on the graphscreen.
:BackgroundOn Image1
is the same as
:BackgroundOn 1
Intrestingly, the following is a valid syntax, which fills the graphscreen with a light blue (18).
:15→B
:BackgroundOn B+3
In addition, BackgroundOn can be used to fill the graphscreen with a solid color. The color variables range from 10 to 24, blue to dark gray, as documented here. For example, BackgroundOn 12 will fill the graphscreen with black.
:BackgroundOn 12
Error Conditions
 ERR:DOMAIN is thrown if the number is not an integer between 0 and 24.

GRAY  23 
DARKGRAY  24 
Each color token is 2 bytes.
The color tokens can be used in calculations. For example, LTBLUE/3 will equal 6.
Background Colors
When the calculator displays text on the graphscreen, it displays it on top of a predetermined background color. This background color is white for all colors of text, except for yellow, white, and light gray (LTGRAY), which have a background color of medium gray (MEDGRAY). If you want to display text in your game without the annoying textbackground, you need to have the graphscreen background be white or medium gray so the textbackground doesn't show. The only known alternative is to use PxlOn to draw the text manually, so how you work around this issue depends almost entirely on how lazy you are. You can see how this works by looking at the image in the Command Summary sidebar.
Error Conditions
 ERR:DOMAIN is thrown if the argument specified is not an integer within the 1024 range.
