This is how to make commands for finding the minimum and maximum number from a set of numbers.

## Setup

First, one will need to create some variables and a list:

```(i)
(min)
(max)
(numbers::list)```

Then, to separate each number into its own item in the list, use the following custom block code:

```define Initialize List (numbers)
delete all of [numbers v]
set [string v] to []
set [i v] to [1]
repeat (length of (numbers))
if <(letter (i) of (numbers)) = ( )> then // Make sure there's a space in the right-hand side of the boolean
set [string v] to () // Make sure there's nothing in this input
else
set [string v] to (join(string) (letter (i) of (numbers)))
end
change [i v] by (1)
end
add (string) to [numbers v] // This block adds whatever's left to the list```

## Find Maximum Number Command

This command has to be called like this: 1 2 3. Typing 1 2 3 finds the maximum number out of 1, 2, and 3. It's possible to add as many numbers in the string.

### Creating the Command

The first step for creating the command is to make a block called Find Biggest Number, then add a number input called Number string, and finally check the "Run without screen refresh" box. Make this code under the define block:

```define Find Biggest Number (numbers)
Initialize List (numbers)::custom
set [i v] to [1]
set [max v] to [-Infinity]
repeat (length of [numbers v])

if <(item (i) of [numbers v]) > (max)> then
set [max v] to (item (i) of [numbers v])
end
change [i v] by (1)
end```

### Using the Command

Now make a script like this one to test the command:

```Find Biggest Number [1 2 3]::custom
say (max)```

If the program is correct, the sprite should say the number 3. If the sprite says no number or another number, check the define block's script.

## Find Minimum Number Command

This command uses a similar approach to the find maximum number command. The command is called the same way as the maximum number command.

### Creating the Command

The first step for creating this command is to make a block called Find Smallest Number, then add a number input called Number string, and finally check the "Run without screen refresh" box. Make this code under the define block:

```define Find Smallest Number (numbers)
Initialize List (numbers)::custom
set [i v] to [1]
set [min v] to [Infinity]
repeat (length of [numbers v])
if <(item (i) of [numbers v]) < (min)> then
set [min v] to (item (i) of [numbers v])
end
change [i v] by (1)
end```

### Using the Command

Now make a script like this one to test the command:

```Find Smallest Number [1 2 3]::custom
say (min)```

If the program is correct, the sprite should say the number 1. If the sprite says no number or another number, check the define block's script.

## Uses for These Commands

They are used for some reasons, like:

1. Finding the maximum or minimum number of a number string.
2. Quizzes where someone guesses the highest or lowest number.
