description: "This quick little program can generate a complementary DNA/RNA sequence for DNA/RNA, and then displays the result. In color!\n\nCurrently functional - it works if you 'play by the rules.' Invalid characters will crash the program, and the display looks strange if you have too small of a sequence.\n\nPlanned: \n1.0 - Main release, character check, will include key on diagram (what color is what base)\n1.0/1.1 - Optimizations and bugfixes, a readme that is 'slightly' helpful (instructions that are mostly self explanator)\n\nTo install, just send the file ACTG.8xp to your TI-84+CSE or TI-84+CE."

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/t-1441297/connect-4. 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 counter-clockwise 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 TI-GBR (rules are explained).

## Version 1: Kahla

— Programmed by kg583 and optimised by the TI-Basic Developer community (see credits for details)
— Compatible on both grayscale and color calculators

## Version 2:

— Programmed by TI-GBR and optimised by the TI-Basic 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 counter-clockwise 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.

After first turn: player 1 has chosen the fourth house from the top, the last stone fell in a well, so player 1 will go again.
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

See development page

THANK YOU to everyone who participated in this community project!

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 Ti-Community, 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[count-1]*ftr→ansList[count]
:EndFor
:For count,1,dim(ansList)
:ansExp+ansList[count]*xexp^(dim(ansList)-count-1)→ansExp
:EndFor
:ansExp-ansList[dim(ansList)]/xexp+ansList[dim(ansList)]/(xexp-ftr)→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.

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.

All Functions must return something using Return

# Examples

Here are a few examples of use.

synthdiv({5,.46,84,.50,7},1/5)
5x3-45x2+75x-35

synthdiv({1,5,6},1)

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 input-ed column, L2 as the height of the columns, And Z as the counter for the possible number of turns.

## Credits

This Game was coded by TI-GBR 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 Ti-Community, with a link to this page for clarification.

Routine Summary

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 (x-r) (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.

Inputs

L₁ - the coefficients of the polynomial you want divide by (x-r)

Outputs

L₂ - the coefficients of the answer and the remainder is stored as the last list entry

Variables Used

L₁, L₂, A, R, Ans

Synthetic division works for problems in the following format.

(a0xn + a1xn-1 + a2xn-2 + … + an-1x1 + anx0) / (x-r)

Where a0≠0

For example,
Problem: find the roots of x3-x2-2x-12=0

First we need to find all possible (r) in (x-r)
Factor an:-12 {±1,±2,±3,±4,±6,±12
Factor a0:1 {±1
List of an/a0:{±1,±2,±3,±4,±6,±12
this last list is the list of all possible r in (x-r)

Now for synthetic division.
See the wikihow website

Using the program.

Input L1 with the polynomial's coefficients, {1,-1,-2,-12→L1
Input R for r in (x-r), 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 (x-r) 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 (x-r) , f(x)= (x-r) * 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 (x-r) is a factor of f(x) and f(x) can be broken down into q(x)*(x-r)

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 (x3-x2-2x-12) / (x-3) = x2+2x+4
(x-3) is a factor of (x3-x2-2x-12
Then use the quadratic formula with x2+2x+4 to find the other factors.

Command Summary

Changes the color of the graph border.

Command Syntax

BorderColor <color#>

Press:

1. 2ND Zoom to access format menu.
2. Scroll down to BorderColor and use arrows.

It can also be found under the catalog.

TI-84+ CSE/CE

2 bytes

There are only 4 borders to choose from, so using the default colors will not work. Instead, you may only use a value between 1-4.

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.

# Related Commands

Command Summary

Changes the color of a certain function.

Command Syntax

GraphColor(function#,color#)

Press:

1. 2ND 0 to access catalog.
2. TAN to get to the G index
3. Scroll down to find GraphColor(, then ENTER to paste.

Graph colors can also be changed under Y=.

TI-84+ CSE/CE

2 bytes

This command will change the color of any function from Y0 to Y9. So, for example, to change the color of Y3 to NAVY, do:

GraphColor(3,NAVY


Notice, you must use the number of the function, rather than the entire function name, which would be Y3.

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


# Related Commands

Command Summary

Turns asymptote detection on.

Command Syntax

DetectAsymOn

Press:

1. 2nd FORMAT to access the graph format menu
2. Use arrows and ENTER to select "On" under "Detect Asymptotes:"

It can also be found under the catalog.

TI-84+ CSE/CE

2 bytes

When DetectAsymOn 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.

# Related Commands

Command Summary

Turns asymptote detection off.

Command Syntax

DetectAsymOff

Press:

1. 2nd FORMAT to access the graph format menu
2. Use arrows and ENTER to select "Off" under "Detect Asymptotes:"

It can also be found in the catalog.

TI-84+ CSE/CE

2 bytes

When DetectAsymOff 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.

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.

# Related Commands

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?

1. abs(-5)
2. -30 / 6
3. int(-5.5)
4. 51
5. 30 / 5

Answer: Choices 1 and 4, which both equal 5.

3. True or False: The complex number i squared is equal to one.

4. Evaluate the following expression. Remember the Order of Operations.

(1)
$$24 / 4 + 2 * (9 - √9) / 3$$

5. Which of the following commands will calculate the number of possible 3-digit number lock codes? The code can use the numbers 0 - 30 and order does matter.

1. 3 nPr 30
2. 30 nCr 3
3. 3 nCr 31
4. 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) = logb(x)

7. Which of the following trigonometric identities is correct?

1. cos(x) - sin(x) = tan(x)
2. tan(x) + cos(x) = sin(x)
3. sin(x) / cos(x) = tan(x)
4. sin(x) * tan(x) = cos(x)

8. The max() command can be used as a space-saving substitute for which kind of logical operator?

Answer: The operator OR. The min() command can be used as a substitute for AND statements.

You can use a technique known as Run-length encoding (RLE) to compress a string. In the example above, this is done by placing a number in front of the consecutive repeated tokens. Str1 is the compressed string, and Str2 is the decompressed string. In Str2, the "2O" in Str1 becomes "OOO", and "3_" becomes "".

This page is dedicated to showcase small snippets of code that may be useful. These small routines are designed to accomplish tasks involving mathematics. Unless specified, output is in Ans.

Primality of Positive Integerjonbush; lirtosiast

This routine works for 3≤X<106 and returns 0 if X is composite, and 1 if X is prime.
If used in an If statement or place where the true value does not matter, you can remove the 0≠.

min(remainder(X,seq(A,A,2,1+√(X

This code can be modified to be faster if X is already known to be odd.
min(remainder(X,seq(A,A,3,1+√(X),2

The following code is faster for large or even X, and works for all 0≤X<3.99*106.
min(X={2,3,5
If X≥7 and fPart(.5X
min(remainder(X,3+2cumSum(not(binompdf(int(.5√(X)),0


Euler's Totient Function Φ(n)kg583

This routine calculates the value of Euler's Totient Function for any integer X>3.

2+sum(seq(gcd(X,A)=1,A,2,X-2


Number of Factorskg583

This routine calculates the number of factors for any integer X>2. A factor is any integer can divide X with no remainder (including 1 and X).

2+Xmean(seq(not(remainder(X,A),A,2,X-2


This page is dedicated to showcase small snippets of code may be useful. These small routines are designed to accomplish tasks involving lists, matrices, and their attributes. Unless specified, output is in Ans.

Index of Maximum List Element – jonbush

This line finds the index of first occurrence of a specific value in a list.
The list to be searched is in Ans at the beginning.

:1+sum(not(cumSum(Ans=max(Ans


This can also be used to find the index of the minimum or of any other value in place of max(Ans

Number of Elements Less than X – kg583

This line counts the number of elements in a list less than some number X.
The list to be searched is in Ans.

:sum(0<Ans-X


Replace < with > to return the number of elements greater than X, for numbers less than or equal to X and for numbers greater than or equal to X.

Shuffle a list

This routine is the fastest way to shuffle a list. L₁ is the list to be shuffled and L₂ is a temporary list used to do the shuffling. Make sure to clean up L₂ after your program.

:rand(dim(L₁->L₂
:SortA(L₂,L₁


Reverse a list – Xeda Elnara

This routine is the smallest way to reverse a list. L₁ is reversed without affecting Ans.

:dim(L₁
:seq(L₁(Ans-K),K,0,Ans-1


Remove list element – jonbush

This routine is the smallest way to remove a single element from a list. The position of the element to be removed from L₁ is in Ans, and the result is a list with that element removed.

:seq(L₁(A+(A≥Ans)),A,1,dim(L₁)-1


Enter List using Input - Trenly

This routine is a way to allow a list to be entered using the Input command. The values to store in the list should be a comma separated string of numbers e.g "1,2,3"

:Input Str1
:expr("{"+Str1→L₁


Nth Occurrence of Element — kg583

This routine will find the index of the Nth occurrence of an element X in a list. If it does not exist, the output will be dim(Ans)+1

:1+Σ(sum(not(cumSum(Ans=X)-K)),K,0,N-1


Partial Probability - Timothy Foster

This routine takes a single list in Ans, and randomly selects an element according to the bin sizes in the list. As an example, if the input is {4,11,2,3,0} there is a 4/20 chance that Bin 1 is chosen, an 11/20 chance for bin 2, 2/20 for bin 3, a 3/20 chance for bin 4, and a 0/20 chance for bin 5.

1+sum(cumSum(Ans)<randsum(Ans


This page is dedicated to showcasing small snippets of code that may be useful. These small routines are designed to accomplish tasks involving numbers and their attributes. Unless specified, the output is in Ans.

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


Number ConcatenationDarkerLine

Returns the number formed by concatenating positive integers M and N.

N+M10^(1+int(log(N


Number of Digits in Nonzero Integer

If X is always positive, remove the "abs(".

1+int(log(abs(X

Input must be a whole positive integer and be less than 1024 due to limit of 10 digits

The finance variables (N,I%,PV,PMT,FV,P/Y,C/Y), window variables (ZXscl, ZYscl, Xscl, Yscl, u(nMin), v(nMin), u(n-1), v(n-1), Zu(nMin), v(nMin), Xmin, Xmax, Ymin, Ymax, Tmin, Tmax, θmin, θmax, ZXmin, ZXmax, ZYmin, ZYmax, Zθmin, Zθmax, ZTmin, ZTmax, TblStart, PlotStart, ZPlotStart, nMax, ZnMax, nMin, ZnMin, ΔTbl, Tstep, θstep, ZTstep, Zθstep, ΔX, ΔY, XFact, YFact, TblInput, w(nMin), Zw(nMin), PlotStep, ZPlotStep, Xres, ZXres), and the sequence variable n are much faster than real variables and Ans (but slower than immediate constants) to access, but take up more space, being two byte tokens instead of one byte real variables. 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 TI-84 series calculator and 1.3 ms on a TI-83 or 83+. After thousands of times accessing the variable, the time can add up.

We pad the string with spaces to prevent a domain error.

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"
converted to lowercase is
"hello world"

"H^:'[]{}/ello* world"
converted to uppercase is
"H^:'[]{}/ELLO* WORLD"

//Finds first occurence of X in L1
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.

Command Summary

Used to display a background image on the graphscreen

Command Syntax

BackgroundOn Image#
Background color

Press

1. 2ND DRAW to access the draw menu
3. Enter or 1 to select BackgroundOn

TI-84+CSE and TI-84+CE

2 bytes

With the introduction of color and a higher resolution screen than the monochrome calculators, the TI-84+CSE and TI-84+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.

# Related Commands

Please see the AsmPrgm page. The functionality and use is the same between both commands. However, the Asm84CPrgm is only available on the TI-84+CSE calculator. Keep in mind that hexadecimal for the monochrome calculators may not work on color calculators.

Command Summary

Press:

1. 2ND PRGM to enter the DRAW menu
2. A to select TextColor(, or use arrows

TI-84+CSE and TI-84+CE

2 bytes

The TextColor( token is used to set the color for Text(. Although the default color is Blue, the calculator saves the color until it is changed again using TextColor( or when a memory reset occurs. When a memory reset occurs, the text color is reset back to blue.

:TextColor(BLUE
:Text(0,0,"THIS TEXT IS BLUE
:TextColor(GRAY
:Text(12,0,"THIS TEXT IS GRAY
:Text(24,0,"THIS IS GRAY AS WELL
:TextColor(12
:Text(36,0,"THIS TEXT IS BLACK


The following table are the colors associated with their numeric values.

Color Token Numeric Value
BLUE 10
RED 11
BLACK 12
MAGENTA 13
GREEN 14
ORANGE 15
BROWN 16
NAVY 17
LTBLUE 18
YELLOW 19
WHITE 20
LTGRAY 21
MEDGRAY 22
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 text-background, you need to have the graphscreen background be white or medium gray so the text-background doesn't show. The only known alternative is to use Pxl-On 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 10-24 range.

# Related Commands

…that the color tokens on a TI-84+CSE/CE can be used as number equivalents for math? For example, BLUE*5 equals 50 while DARKGRAY-4 equals 20?

The program might have a few bugs (I programed it from scratch on my friend's calculator, so I don't have it with me), so if you find any bugs, please edit this page to remove them if you can figure out where they are.\n\nInstead of the game plainly ending when you die, it returns an error message.\n\nPlease comment if there is something wrong with the program.\n\nNote: The download link doesn't work, you'll have to type in the code by hand.\nEDIT: I borrowed my friend's calculator, here is the actual coding: (other coding was deleted)\nANOTHER EDIT: Now has a scoring system\n\n[[code]]\n:1→Y\n:16→A\n:1→B\n:5→E\n:0→Z\n:Lbl G\n:getKey→K\n:A-1→A\n:randInt(2,7)→D\n:ClrHome\n:If not(A:16→A\n:If not(A=16:0→B\n:If A=16:1→B\n:If B=1:D=E\n:If K=25:Y-1→Y\n:If not(K=25:Y+1→Y\n:Output(Y,3,\"0\n:For(I,1,8)\n:Output(I,A,\"H\n:End\n:Output(E,A,\" \"1 space\n:Output(E+1,A,\" \"1 space\n:If A=3\n:Then\n:If not(Y=E) and not(Y=E+1\n:Output(10,10,\"P\n:Output(1,8,Z\n:Z+1→Z\n:End\n:Goto G\n[[/code]]"
