Several (around 3) commands have a similar function or are used in a similar context to this command. Make a bulleted list of them, with links to the other commands' pages. It will often be the case that several commands all link to each other.

fPart(*value*) returns the fractional part of *value*. Also works on complex numbers, lists and matrices.

```
fPart(5.32)
.32
fPart(4/5)
.8
fPart(‾5.32)
‾.32
fPart(‾4/5)
‾.8
```

# Advanced Uses

fPart(, along with int( or iPart(, can be used for integer compression.

Also, fPart( is an easy way to find A mod B (the positive remainder when A is divided by B).

`:B(A<0)+iPart(BfPart(A/B))`

If A is guaranteed to be positive, the following shorter code can be used, omitting B(A<0):

`:iPart(BfPart(A/B))`

Finally, the easiest way to check if a number is a whole number is not(fPart(X:

```
:If not(fPart(X:Then
: // X is an integer
:Else
: // X is not an integer
:End
```

You can use this, for example, to check if a number is divisible by another: if X is divisible by N, then X/N is a whole number. This is useful when you want to find the factors of a number. Warning: when storing values with repeating decimals and later multiplying them to see if a number makes it an integer it can return a value of 1 or -1 instead of 0 even if it is an integer. Example: if you store 1/3 as X and then do fpart(3x) it will return 1 instead of 0. This is because fpart(.999…) results in .999… and then rounds to 1 when displaying rather than rounding to 1.0 and then displaying the fpart( as 0.

# Optimization

Often you want to find the value of a-1 mod b — this occurs, for example, in movement routines with wraparound. However, the problem is that if a=0, a-1 will be negative. Rather than use the longer version of the modulo routine, you might replace subtracting 1 with adding (b-1). This will have the same result, but without sign problems.

A short description of what the command does.

The generic syntax of calling the command, with arguments.

The `Ans` variable holds the last answer that was stored in the calculator. Because `Ans` is stored in a special storage area built-in to the calculator, and it is extensively used by the calculator, you cannot delete it. Ans is also useful; it can make your programs both smaller and faster:

- Unlike other variables which have a value type hard-coded in (i.e., a string can only hold text, and lists and matrices can only hold numbers),
`Ans`can take on whatever value you want: a real or complex, list, matrix, or string are all acceptable. - Along with the finance variables,
`Ans`is faster than the real, complex, list, matrix, and string variables; and subsequently, you should try to use it as much as possible.

One of the most common places to use `Ans` is in place of storing a value to a variable. Just paste the `Ans` variable to the location where the variable was called, and then when the expression is evaluated, the calculator will use the current value of `Ans`. Using the `Ans` variable allows you to eliminate the variable, which helps save a little or a lot of memory (depending on the type of variable and its size).

```
30+5A→B
Disp 25A,30+5A
;can be
30+5A
Disp 25A,Ans
```

The one major drawback to using `Ans` is that its current value is only temporary. Whenever you store a value to a variable or place an expression or string on a line by itself, `Ans` is updated to the new value. This restriction essentially limits your use of `Ans` to only a single variable. If you are manipulating two or more variables, it's best to just use the variables.

There are several cases in which changing the value of a variable does not modify `Ans`, thus preserving its current value for later use:

- storing to an equation variable
- using the
`DelVar`command to delete a variable (i.e., set its value to zero, if it's a real variable) - initializing or changing the value in a
`For(`loop.

These cases can be very useful, allowing you to use Ans to store an expression rather than create a temporary variable for it.

A list is a collection of elements (made up of numbers, variables, or expressions). Although lists can have up to 999 elements (the only exception is the TI-83, which can only have 99 elements), they are limited by the amount of free RAM. Besides the six built-in lists (from L_{1} to L_{6}), which can be accessed by pressing [2nd] and [1] to [6] (for whichever list you want), you can also create custom lists. A custom list name can be one to five characters, comprised of any combination of capital letters and numbers and theta, but it must begin with a letter or theta.

Lists are very versatile variables. They are used for storing highscores and map information, and just about anything else. Lists are also important because they are the only variable that can be assigned a name. This adds a certain security to using them. Other programs can still access your lists (and change or corrupt them), however, but there is a smaller likelihood of this happening simply because there are millions of possible names available.

To use lists, you must become familiar with some specifics of their syntax:

- The little ∟ command, which belongs at the beginning of any list name, except the default lists L
_{1}…L_{6}. Almost always, when using a list, you must include this: e.g., to access the list SCORE, you would enter ∟SCORE. When you choose a list from the [2nd][LIST] menu, this is added by default so you don't have to worry about it. - The curly brackets: { and }. These allow you to manually enter a list. When manually writing a list, you begin with putting a single opening curly brace ({) that will enclose the list. You then type a number or variable or expression, and put a comma after it. You repeat this for however many elements you want. You then put a single closing curly brace (}) that will close the list.
- Parentheses: ( and ). These access a specific element of a list: for example, ∟NAME(5) would be the 5
^{th}element of ∟NAME. You can also use this to store to an individual element of the list.

# Commands

List variables stand out from other advanced variable types because most commands you can use for numbers can be used for lists as well. In such a case, the command will be applied to each element of the list individually, and a list of the results will be returned. If two lists are used like this in the same command, their elements are "paired up" and the command will be applied to each pair. For example:

```
:cos({30,60,90
will be evaluated like
:{cos(30),cos(60),cos(90
```

```
:{3,4,5}={6,7,5
will return
:{0,0,1
```

Before doing any list comparison operations, you should first check that both list dimensions are the same size using the dim( command. This check is necessary because if the lists are not the same size, it will cause an ERR:DIM MISMATCH error. Of course, if you can guarantee their sizes will be identical, you can leave off the size check.

```
:If dim(L1)=dim(L2
:Then
:If min(L1=L2
:Disp "EQUAL
:End
```

There are some special commands for lists; some can be used for normal commands as well, but have a special meaning when used for a list. These are typically accessed through the [2nd][LIST] menu, and include:

Some statistical commands are used with lists as well: see the Statistics page for details.

# Optimization

Some optimization tricks are used specifically with lists. For example, you may sometimes omit the little ∟ symbol at the beginning of a list. The most common situation where this applies is when using the → (store) command to store to a list. For example:

```
:{1,2,3→∟NUMS
can be
:{1,2,3→NUMS
```

This is even possible with a single-letter name, such as ∟X: the calculator will realize that you did not intend to store to the real variable X because lists cannot be stored to a real variable.

Another optimization that is possible is storing to the element just past the end of the list. For example, if ∟X has 5 elements, storing to ∟X(6) is also allowed. This increases the size of ∟X to 6 elements, and then sets its 6^{th} element as usual. The following is a standard construction to add an element to the end of a list:

`:(value)→∟X(1+dim(∟X`

You can even store to the first element of a list that doesn't exist. Because there are no elements in the list, the calculator will first create a new element at the beginning of the list, and then assign it the value. This optimization works especially well when looping with a For( loop, since you can use the loop variable as the list index.

# Advanced Uses

Lists can be linked together in a way similar to an Excel spreadsheet using a quotation mark:

`:"2L₁→L₂`

After running this code, modifying a value in L1 will cause the corresponding element in L2 to be updated accordingly. Modifying a value in L2 will break the link. Connected lists are indicated by a ♦ symbol in the list editor on the TI-84+, and by a small lock on the TI-84+CE.

Returns the minimum of two elements or of a list.

- for two numbers: min(
*x*,*y*) - for a list: min(
*list*) - comparing a number to each element of a list: min(
*x*,*list*) or min(*list*,*x*) - pairwise comparing two lists: min(
*list1*,*list2*)

min(*x*,*y*) returns the smallest of the two numbers *x* and *y*. min(*list*) returns the smallest element of *list*. min(*list1*,*list2*) returns the pairwise minima of the two lists. min(*list1*,*x*) (equivalently, min(*x*,*list1*)) returns a list whose elements are the smaller of *x* or the corresponding element of the original list.

```
min(2,3)
2
min({2,3,4})
2
min({1,3},{4,2})
{1 2}
min({1,3},2)
{1 2}
```

Unlike relational operators, such as < and >, min( can also compare complex numbers. To do this, both arguments must be complex — either complex numbers or complex lists: min(2,*i*) will throw a ERR:DATA TYPE error even though min(2+0*i*,*i*) won't. In the case of complex numbers, the number with the smallest absolute value will be returned. When the two numbers have the same absolute value, the second one will be returned: min(*i*,-*i*) returns -*i* and min(-*i*,*i*) returns *i*.

# Advanced Uses

min( can be used in Boolean comparisons to see if every value of a list is 1 (true) — useful because commands like If or While only deal with numbers, and not lists, but comparisons like L1=L2 return a list of values. In general, the behavior you want varies, and you will use the min( or max( functions accordingly.

Using min( will give you a strict test — only if every single value of a list is true will min( return true. For example, the following code will test if two lists are identical — they have the same exact elements — and print EQUAL in that case:

```
If dim(L1)=dim(L2
Then
If min(L1=L2
Disp "EQUAL
End
```

The first check, to see if the sizes are identical, is necessary because otherwise comparing the lists will return a ERR:DIM MISMATCH error.

# Error Conditions

**ERR:DATA TYPE**is thrown when comparing a real and a complex number. This can be avoided by adding 0*i*to the real number.**Dimension Mismatch**is thrown, when using min( with two lists, if they have different dimensions.

# Related Commands

Exclusive or statement. Returns the truth value of value1 or value2, but not both, being true.

value1 xor value2

**xor** takes two numbers of expressions and checks to see if *exactly one* is True. If both are True or both are False, it returns 0.

```
1 xor 0
1
:2 xor (3 xor 0) (after evaluating 3 xor 0, it simplifies into True xor True.)
0
:0 xor (1-1)^2
0
```

## Table of Results

For reference, the following true/false table shows what gets returned when you use different combinations of 1 (true) and 0 (false):

xor | 1 (true) | 0 (false) |
---|---|---|

1 (true) | 0 (false) | 1 (true) |

0 (false) | 1 (true) | 0 (false) |

Computes the angle of a complex number or a set of complex numbers.

**angle(***Expr1***)** → *expression*

**angle(***List1***)** → *list*

**angle(***Matrix1***)** → *matrix*

The **angle(** command computes the angle of a complex number, which corresponds to the rotation of a vector whose length is equivalent to the **abs(** of the number. The angle is returned in degrees, gradians, or radians, depending on the mode the calculator is in.

```
Degree mode
:angle(1+i) = 45
Radian mode
:angle(1+i) = π/4
```

**angle(** can also return the angles for a list or matrix of complex numbers, returning the outputs in a list or matrix respectively. **angle(** will attempt to return a closed-form expression for the value rather than a decimal expression when utilizing the CAS, and can also return a symbolic evaluation of an angle.

`:angle(z) = π(sign(z)-1)/2`

# Formulas

The general formula for the angle of complex number *x+iy* is given by

Often denoted as θ, the angle of a complex number is used in its polar representation

Boolean AND comparison of expressions or groupings of expressions.

*BooleanExpr1* **and** *BooleanExpr2*

*BooleanList1* **and** *BooleanList2*

*BooleanMatrix1* **and** *BooleanMatrix2*

*Integer1* **and** *Integer2*

The **and** command compares two Boolean expressions (or lists or matrices of expressions) and performs the logical AND comparison, where the output is TRUE if and only if both inputs are also TRUE.

Command | Output |
---|---|

0 and 0 |
0 |

1 and 0 |
0 |

0 and 1 |
0 |

1 and 1 |
1 |

**and** can also be used to simplify logical conditions. For example,

```
:x≥3 and x≥4
outputs
:x≥4
```

because, in order to satisfy both logical conditions, *x* need only satisfy *x≥4*. **and** can perform this process on a list or matrix of Boolean expressions:

```
:{x≥3,x≤0} and {x≥4,x≤-2}
outputs
:{x≥4,x≤-2}
```

which is the intersection of two inequalities. This can be thought of as the overlap of two regions of a number line, where *x* must lie in order to satisfy all of the logical conditions simultaneously.

**and**'s final use is for bitwise comparison of integers. Consider two integers, 24 and 17, which when converted to binary become 0b11000 and 0b10001 respectively. To compare the two integers, **and** compares each bit of the binary number, outputing 1 when both bits are 1 and 0 otherwise:

```
0b11000: 24
0b10001: 17
----- --
0b10000: 16
```

Integers can be entered in any base for use with **and**, including binary (0b) and hexadecimal (0h). The output will match the base of the inputs (if they are identical), defaulting to decimal.

This routine randomly selects a number given a list of partial probabilities

*L₁* - The bin sizes of the partial probabilities

*C* - Which bin is selected

The variables used in the routine.

End
End

```

This routine takes a single list, and randomly selects an element according to the bin sizes in the list. It copies the list so as to not overwrite the data. It then sums the list, and takes the inverse of the sum to use as an interval. It then generates a random number between 0 and 1. By testing if this number falls within the intervals defined by each partial probability, it determines which bin the random number falls into.

As an example, if the input is {4,11,2,3} there is a 4/20 chance that Bin 1 is chosen, an 11/20 chance for bin 2, 2/20 for bin 3, and 3/20 for bin 4. If a bin size is 0, it will be skipped and never selected as the probability is 0.

Finds specific text in a string and replaces all occurrences with replacement text.

*Str1* - The main string to modify

*Str2* - What to search for

*Str3* - What to replace with

*Str1* - the modified string

Str1, Str2, Str3, I, J

TI-83/84/+/SE/CSE/CE

If I+J<1+length(Str1

End
```

First, note that the input for the search string (Str2) and replacement string (Str3) can be modified for however you need them to be input. In this case, the texts "SEARCH" and "REPLACE" have been used as examples for these 2 strings.

To start off, we first store the length of the search string in variable J. Then, we check if the search string can be found in the main string. If not, the loop doesn't continue to run. Otherwise, we store the index in the string where the search string was found in variable I.

After this, we have to account for 3 distinct options:

1. The search string was found at the beginning of the main string

2. The search string was found at the end of the main string

3. The search string was found somewhere in the middle of the main string

So, we first put Str3 in Ans.

Then, if some of the string exists before the search string (so I>1), we add the replacement string in Ans onto that text.

After that, we check if the string exists after the search string (so I+J<1+length(Str1)), and if so, we add the rest of the text onto Ans.

After modifying the string like this, the program then checks if there are any more occurrences of the search string in the main string. If so, this whole process is repeated over.

Calculates the binomial cumulative probability, either at a single value or for all values

for a single value:

binomcdf(trials, probability, [lower_bound,] upper_bound)

for a list of all values (0 to trials)

binomcdf(trials, probability)

From inside a document:

Press Menu, then scroll to probability.

Press the right arrow, then scroll to Distributions.

Press the right arrow, then scroll to Binomial Cdf (B)

This command is used to calculate the binomial cumulative probability function. In plainer language, it solves a specific type of often-encountered probability problem, that occurs under the following conditions:

- A specific event has only two outcomes, which we will call "success" and "failure"
- This event is going to repeat a specific number of times, or "trials"
- Success or failure is determined randomly with the same probability of success each time the event occurs
- We're interested in the probability that there are
**at most**N successes

For example, consider a couple that intends to have 4 children. What is the probability that at most 2 are girls?

- The event here is a child being born. It has two outcomes "boy" or "girl". In this case, since the question is about girls, it's easier to call "girl" a success.
- The event is going to repeat 4 times, so we have 4 trials
- The probability of a girl being born is 50% or 1/2 each time
- We're interested in the probability that there are at most 2 successes (2 girls)

The syntax here is `binomcdf( trials, probability, value)`. In this case:

`binomcdf(4,.5,2)`

This will give .6875 when you run it, so there's a .6875 probability out of 4 children, at most 2 will be girls.

If you wanted the probability that at least 1 and at most 2 will be girls, the syntax would be:

`binomcdf(4,.5,1,2)`

Another alternate syntax for `binomcdf(` leaves off the last argument, *value*. This tells the calculator to compute a list of the results for all values. For example:

`:binomcdf(4,.5`

This will come to {.0625 .3125 .6875 .9375 1} when you run it. These are all the probabilities we get when you replace "at most 2 girls" with "at most 0", "at most 1", etc. Here, .0625 is the probability of "at most 0" girls (or just 0 girls), .3125 is the probability of at most 1 girl (1 or 0 girls), etc.

Several other probability problems actually are the same as this one. For example, "less than N" girls, just means "at most N-1" girls. "At least N" girls means "at most (total-N)" boys (here we switch our definition of what a success is). "No more than", of course, means the same as "at most".

When this happens, the offending page will link here so we can properly apologize, clarify what is meant, and give the syntax that displays them correctly where it is possible to do so.

Here are the commands and symbols that suffer from this problem:

# See Also

- The wiki syntax description on www.wikidot.com.

This page should contain a list of all the errors from the ti-nspire. Would like it set up similarly to errors

This table lists all the possible error messages that can occur. The error number to the left is not displayed, but is stored to the errornum system variable, which can be used in a Try..EndTry block. Some error messages are very explicit (like #680), but others are less so. Where the error message itself gave too little information, this table explains the error more thoroughly.

A large part of the information here was taken from the Nspire CX Reference Guide at education.ti.com

Errors need to be added to the table below. Please alternate between using error1 and error2

In general, omitting all the variables for a section is the way to go if you don't want the section to be displayed. The exception is "calculator compatibility" - omitting the variables for that section will display the default message (compatible with all calculators).

## |picture=

If the image is embedded on the same page, then only the full name of the image is to be written here. Otherwise, simply paste the full URL of the image.

## |summary=

Just type in a brief description of the command.

## |syntax=

Enter the general syntax of the command.

## |compatibility

If the command works on all calculators, simply say "All calculators." Otherwise, specify which calculator(s) the command is compatible with.

Only one option can be applied (and they are exclusive of each other), otherwise unpredictable results may occur.

A short description of what the command does.

The generic syntax of calling the command, with arguments.

Describe how to get the command from a menu.

(Include this disclaimer if command xxxxx doesn't appear correctly due to markup limitations. See *iff* for an example)

NOTE: Due to the limitations of the wiki markup language, the xxxxx command on this page does not appear as it would on the calculator. See Wiki Markup Limitations for more information.

A complete description of the basic uses of the command. All commonly used and documented ways of calling the command should be listed here; inputs, outputs, and anything else important should be mentioned.

```
:At least one piece of example code
:should be included here.
```

# Advanced Uses

Advanced uses include rarely used or undocumented ways of calling the command in question. If there's an unusual but effective way of using the command, that too should be listed. Another type of advanced use is a programming technique to which the command is critical. Finally, system variables modified by the program should be listed here. With each advanced use, you should have a piece of example code to show how it works, as well as an explanation.

If there is already a page on the advanced use of the command, give a short synopsis, then link to that page - you shouldn't include the entirety of that page here.

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:

```
:unoptimized code
can be
:optimized code

# Formulas

(this section is usually not present)

This section is unnecessary for most commands. The only ones that would require it are the ones on the high end of mathematical complexity, such as the statistics commands. Use the math template to type in a LaTeX formula that matches the rest of the page in background. For example, type **[[include inc:nspire-math eqn = \sum_{i=1}^n\frac{a}{r^i}]]** to get:

# Error Conditions

For the non-generic errors that might occur when using this command (that is, syntax-type errors shouldn't be included). In a format similar to the following:

**ERR:DIM MISMATCH**is thrown if the two list arguments have different dimensions.**ERR:RESERVED**is thrown if ∟RESID is supplied as an argument.

# Related Commands

Several (around 3) commands have a similar function or are used in a similar context to this command. Make a bulleted list of them, with links to the other commands' pages. It will often be the case that several commands all link to each other.

- Command 1
- Command 2
- Command 3

This routine uses the List Frequency routine to find the frequency of each number. It then deletes, and reconstructs L₁ from the values in those lists by searching for the highest frequency, then adding it into L₁ the number of times it occurs. It then shifts the elements inside the frequency lists above the value down 1, overwriting the value which was just inserted into L₁. It then decreases the length of the frequency lists, and repeats until there are no more values to be added. This routine automatically cleans up, leaving L₂ and L₃ empty. If you wish to sort in ascending frequency, change the max( on line 12 to min(. If you wish to sort the values in ascending order instead of descending order, change the SortD( on line 1 to SortA(

This menu is made for the graphscreen on monochrome calculators. It functions similarly to the Menu( command, in that it highlights the current menu option, and uses labels. To create your own menus, each menu needs a menu id, a string containing entries of the same length, the number of entries, the length of the entries, and the starting selection. What makes this code functional is that each menu option is referenced by a menu ID, and the number of the selection. Because of this, the same code can be used to display multiple menus.

In addition to the up and down arrows and enter, a user can use the numberpad to select an option. The clear key will exit the program from any menu, and the delete key will return to the main menu from inside any menu. If the delete key is used on the main menu, the program will end.

The main menu has an ID of 0 by default, and can be shown at any time using "Goto M0". Any sub-menus you wish to add should be in the following format. You will need to change O, L, and N for each menu. In the code below, O is set to 1. This is what gets referenced in the If statements in the main code. S is set to 1 since I want the first option to be selected when we load the menu. L is set to 22 in this example because each menu option is 22 characters long. You will notice there are spaces included to make sure each item is the same length. Finally, there are 6 options in this example, so N is set to 6. We then Goto M to display the menu

Example of Inputting Hex Code

There are all sorts of small assembly programs that you can create simply using the calculator's built-in 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.

# Introduction

Celtic III is a Flash Application for the TI-83 Plus, TI-83 Plus Silver Edition, TI-84 Plus, and the TI-84 Plus Silver Edition graphing calculators, designed to extend the functionality of these calculators so that BASIC games and utilities can perform actions that cannot easily be done through the language itself. Celtic III supports its own command set focused more on file handling and manipulation. It also supports a command set used for manipulating image files and screen data. It also supports decent compatibility with the popular xLIB library so you don't have to change anything.^{1}

When programming, you may find that you want to execute a piece of code based on if another section of code has been executed. The easiest way to do this is to use a flag. What exactly is a flag? A flag is typically considered a placeholder or variable which contains a binary or Boolean value. In TI-Basic, it is typically a variable which holds a value of 0 or 1. This variable is called a flag because it is either up (1), or down (0). Flags can be very useful when used in the proper circumstance; They can help prevent double conditionals, allow for the program to behave differently based on which sections of code it has already run, or even change what a program does altogether. Let's look at an example:

```
prgmFLAG
:0→F
:Lbl 1
:Disp "Flag is"
:If F:Disp "Up"
:If not(F:Disp "Down"
:1→F
:If not(F:Goto 1
```

In the code above, we see a very basic flag. The flag is either up, 1, or down, 0. The program will display that the flag is down, set it to be up, then say that it is up before exiting. That's a great start, but how can flags be used in more useful ways?

## Recycled Flags

Recycled flags are flags that are used more than once for the same purpose inside of a program. They are commonly used within loops, but can be used in other ways depending on what you are attempting to do. Consider the following: You have a variable A which you want to compare to B; If A is greater than B, you want to display a message. The only catch is, if A is greater than 50 you want to display a different message. This is a perfect place for a Recycled flag, especially if you want to repeat the comparison with different values. Take a look at the following code:

```
prgmACOMPB
:randInt(1,50→B
:Repeat A=B
:1→T
:Prompt A
:If A>50
:Then
:Disp "A is Greater than 50"
:0→T
:End
:If T(A>B):Disp "A is Greater than B"
:If A<B:Disp "A is Less than B"
:End
```

Did you understand how it worked? If not, let me walk you through it. As you may have guessed, this is a very simple guess the number game. First, we store a value to B. This value doesn't particularly matter, but we want it to be 50 or less for this game. We create a repeat loop that will run until we enter the value of B. Next, we set our flag. I put this flag setting inside the repeat loop, since we want it to reset every time we enter a new number. The program will then ask the user for a value of A to test, and now this is where the flag comes in. The program tests if A is above 50, in which case it would be out of the range of values of B. If A is greater than 50, it displays that and sets our flag to 0, or turns it off. The next conditional tests if A is greater than B. If A is greater than 50, it will always be greater than B, but since we already determined if it was greater than 50, we don't want to accidentally display a message twice. If you take a close look at the statement, we are testing "If T(A>B)" which can be rewritten as "If T and A>B" or even "If T≠0 and A>B". Lets step back and look at the values of when we compared A to 50. If A was greater than 50, T got set to 0; If A was less than or equal to 50, T was left as 1. This means that the statement we are testing will only be true if A is less than or equal to 50 based on the value in T.

## Solitary Flags

The flag in the last example was a recycled flag, meaning we used it multiple times. This is debatably the most common form of flags. The other type of flag is a solitary flag, or a flag that is only used once. Perhaps the best example of this is a program where the author wants the user to do something before running the program. A flag may be used to allow the program to give instruction to the user before executing the code.

```
If A
Then
ClrAllLists
Output(1,1,"Please enter data in L₁
Delvar A
Pause
Return
End
Disp mean(L₁
1→A
```

While this is another simple piece of code, it displays a solitary flag very well. This program displays the mean of L₁, however we know that if there is no data in L₁ this code will throw an error. Lists are one of the variables that cannot be directly stored to using input or prompt, and because of this we want to tell the user to enter their data into the list. This code checks to see if there is a value stored in A, and if there is it then tells the user to enter the data, sets the flag, and exits. The reason this code checks to see if there is a value in A rather than if there is not a value in A is due to the fact that there will be a value in A most of the time. This program, for the flag, sets A to 0 by deleting it once it has told the user where to enter the data. When the program is run again, presumably after they have entered their data, it will see that there is no value and will then display the mean of L₁ as intended before finally putting a value back into A so it can be run again.

This is a program that is like the Pen command.

Let's make a program that could define the variable B, as (10^10). Let's start!

```
Count()
:Prgm
: Local a,b
: 10^10→b
: For a,1,b
: Disp a
: EndFor
:EndPrgm
```

Let's break this code down piece by piece starting from the beginning.

```
counting()
:Prgm
```

The first code is the title of the project called "Count()" but you could make it whatever you want. While the second code is ": Prgm", which let's the calculator understand that it is a "program".

```
: Local a,b
: 10^10→b
: For a,1,b
: Disp a
```

In this code, a "For loop" is established, which will store each successive number from 1 through B (10^10) in variable A.The program then outputs the data currently stored in Variable A, to character space 1,1 in the screen

```
: EndFor
:EndPrgm
```

For this segment, "EndFor" ends the for loop after the code is executed. While "EndPrgm" ends the code.

…that you can use a combination of real and imaginary numbers to compress a real list, and use `imag(` and `real(` to decompress it?

…that you can use plot sprites to make simple, easily movable sprites on the color calculators?

If you haven't read Your First Program yet, I recommend you do so first.

## Indentation

Whenever you write TI-Basic code, you should make sure it's readable. This will help both yourself and others in the future. One way to make your code more readable is to use indentation. Indentation is important because it allows you to easily see when one block of code ends and the next begins. Squashing all your code together with no indentation can make it hard to read.

Indentation is usually done with one space per level. The calculator keeps track of how many spaces begin a line, so they will survive being tokenized. When you begin a block, such as If, or Loop, or While, you add a level of indentation to lines after it, and remove it when you reach an 'End', such as 'EndIf', 'EndLoop', or 'EndWhile'. Here's an example of good indentation:

```
:indtexmp()
:Prgm
: © Prgm begins a block, so the rest of the code is indented
:
: Loop © Loop also begins a block, so add an indentation level
: If getKey()=13 Then
: Exit
: EndIf
:
: Disp "Hello, World!"
: EndLoop © EndLoop ends the block, so remove the indentation level
:EndPrgm © EndPrgm is not indented at all
```

Indentation is going to be hard to maintain on a real calculator, or in many TI-Basic editors, since it isn't too common in the TI-Basic community. However, it will be worth it when you're working on a large program. Notice the blank lines before and after blocks like Loop. Like indentation itself, it is entirely optional and it only assists in reading the code. Here's an example of no indentation:

```
:noindent()
:Prgm
:Loop
:If getKey()=13 Then
:Exit
:EndIf
:Disp "Hello, World!"
:EndLoop
:EndPrgm
```

This is a simplified example. Imagine an application with 10 or 15 nested If statements, each with their own Else and ElseIf statements. Now imagine needing to put code inside a specific If. You will most likely need indentation to keep track of where to put the code, or you might just sit there for a while trying to make sense of all those nested Ifs!

It should be clear that indentation isn't required. Most members of the community don't use it for their programs, maybe because it increases program sizes, or because it's cumbersome to maintain. Maybe it just isn't worth the effort. You should decide whether indentation is for you. You could indent because it makes code more readable, or even just because you're used to indenting code. To indent, or not to indent? That is the question, and the reasoning for your answer is up to you.

…that 68k calculators can not only program in TI-Basic, but can program in Assembly and C as well?

There are no new updates.

This is a Celtic 3 program that allows you to do things that a Non-Celtic 3 program would do. Requires Celtic 3 to be installed, and requires at least 3000 bytes of RAM to use (even when you run the program, a little ram [130 bytes] is taken away when a program is ran)

`Rcl` is a functionality of the calculator which allows the user to paste the value of a variable into a text entry field. The `Rcl` function can be used anywhere where text entry is required, but may not be used as a command within a program. When the user presses [2ND][STO>], the `Rcl` prompt will appear. Enter the name of the variable that you wish to recall here, and press [ENTER]. For example, you could use Rcl to paste the contents of a string variable into an Input prompt in a running program.

`Rcl Str1`

# Advanced Uses

`Rcl` can be used to paste one program into another program, allowing for duplicating programs on the calculator. This is particularly useful when modifying a working program. If you decide that your changes should be reverted, you will have a backup copy of the original program

# Related Commands

This code finds the angle of intersection of two lines.

Finds the angle of intersection for any two lines.

Str1 and Str2

Ans

Y1, Y2, I, Ans, X

TI-83/84/+/SE/CSE/CE

```
:Degree
:Str1→Y1
:Str2→Y2 \\If your equations are already stored in Y1 and Y2, these two lines are unneccessary
:E‾9→I \\This threshold can be changed to adjust the output accuracy
:angle(I+i(Y2(X+I)-Y2(X
:Ans-angle(I+i(Y1(X+I)-Y1(X
:Disp "ANGLE OF INTERSECTION IS",Ans
```

The routine works by assuming the graphs are almost straight lines at a very small scale around the point of intersection given by X. The two graphs are approximated by complex numbers made by combining the x and y coordinates. The angle( command finds the angle for each complex number, then they are subtracted. This command is useful as it avoids domain errors caused by using tanֿ¹(.

If you do not already know the x-coordinate of the intersection of the two graphs, you can add this line at the beginning to find it:

`:solve(Y2(X)-Y1(X)=0,X,0→X`

Graphs up to 5 piecewise expressions.

(expression, condition [,expression, condition])

Up to 5 (expression,condition) pieces are allowed.

1: While editing a program, press [math]

2: Then press [alpha] [apps] (B) or scroll down.

TI-84+CE OS 5.3

2 bytes

The `piecewise(` command is a new addition in the release of OS 5.3 for the TI-84 Plus CE. As implied, it allows for the graphing of piecewise functions in the Y= editor. The example code demonstrates how this works from within a program.

```
:ClrDraw
:Input "Y1=",Str1
:Input "Y2=",Str2
:Str1→Y1
:Str2→Y2
:FnOff
:"piecewise(Y1,X≥0,Y2,X<0→Y3
:DispGraph
```

# Advanced Uses

One use of the `piecewise(` function is to evaluate an expression for a given value of X. For example:

`:piecewise(X²+2,X≥0`

This code will return the value of the expression if X≥0. So if X=0, then the program will return a value of 2. If X=3, it will return a value of 11. If X=-5, it will return an error.

# Optimization

This command can simplify and compact the usage of piecewise expressions in programs. If you have less than 6 conditions that will never overlap, and they all affect a single variable, you can use the `piecewise(` command to make your code smaller, as shown below. Beware of comparability, though.

```
:If X<2
:Then
:4.5X→N
:Else
:8X+3→N
:End
can be
:piecewise(4.5X,X<2,8X+3,X≥2→N
```

# Error Conditions

**ERR:INVALID**is thrown if expressions are not defined.**ERR:DATA TYPE**is thrown if a quotation mark is not placed before a piecewise command that is to be stored to an equation variable.
