A *String* is a sequence of characters. For the BBC micro:bit, ASCII character codes 32 to 126 are supported; letters, digits, punctuation marks, and a few symbols. All other character codes appear as a ? on the [LED screen](/device/screen).

### Create a string variable
|
|
|
|
```block
|
|
salutation = "Hello";
|
|
```
|
|
|
|
To create a variable that holds a string:
|
|
|
|
1. Click `Variables` (in the Block drawer).
|
|
|
|
2. Type a name for your new string variable by clicking the down arrow, then click New Variable. Then type the variable name "salutation"
|
|
|
|
2. Drag a string block on the right side of the operator.
|
|
|
|
3. Click `"Hello"` and then type a string like `hello`.
|
|
|
|
Your code should look something like this:
|
|
|
|
```block
|
|
salutation = "Hello";
|
|
```

### The function `show string`
|
|
|
|
Use [show string](/reference/basic/show-string) to display a string on the [LED screen](/device/screen).
|
|
If the string is multiple characters, the string scrolls right to left. The following example displays `Hello world!` on the micro:bit screen:
|
|
|
|
```block
|
|
basic.showString("Hello world!");
|
|
```
|
|
|
|
The parameter of `show string` specifies the string
