# Mid

This is a pre-built Action located under the **@Generic Element**. The functionality of this Action in Avo Assure is to extract the middle character from the given input text. The extracted character is stored in a dynamic variable.

## **Syntax**

**Input Value**: `<string>`&#x20;

{% hint style="info" %}
**Note**: If the input string is provided in even number of characters, then it returns the mid+1 \[(length/2) + 1] value.
{% endhint %}

| Argument                          | Description                                                           |
| --------------------------------- | --------------------------------------------------------------------- |
| <p>\<string></p><p>(Required)</p> | Provide the string from which the middle character will be extracted. |

**Output Value**: `<Dynamic Variable>;<Dynamic Variable>(Optional)`

| Argument                                     | Description                                                       |
| -------------------------------------------- | ----------------------------------------------------------------- |
| <p>\<Dynamic Variable></p><p>(Required)</p>  | This dynamic variable holds the extracted middle character.       |
| <p>\<Dynamic Variable></p><p>(Optional) </p> | This dynamic variable stores the status as **True** or **False**. |

### **Example 1: Extracting the Middle Characters from a String**

In this example, we explain how to extract the middle portion of a string using.

* **Action**: Mid
* **Input Value**: Michael Brown
  * This specifies the string from which the middle character is extracted
* **Output Value**: {Mid String}
  * The extracted middle portion of the string (l) is stored in this **{Mid String}** dynamic variable for further use.
  * If the second output variable is defined, it stores the action status with the following possible values:
    * **True**: If the middle character is successfully extracted.
    * **False**: If the extraction fails due to invalid input or configuration.
* **Logical Explanation**: The **Mid** action fetches the value from the **Input Value** column (**Michael Brown**) and extracts the middle character from the string which is (l). The extracted middle portion is stored in the **{Mid String}** variable.

### **Example 2:** Extracting the Middle Character from an Even-Length String

In this example, we explain how to extract the middle character from an even-length string.

* **Action**: Mid
* **Input Value**: Emma
  * This specifies the string from which the middle character is extracted.
* **Output Value**: {Mid String}
  * The extracted middle character (m) is stored in this **{Mid String}** dynamic variable for further use.
  * If the second output variable is defined, it stores the action status with the following possible values:
    * **True**: If the middle character is successfully extracted.
    * **False**: If the extraction fails due to invalid input or configuration.
* **Logical Explanation**: The **Mid** action fetches the string from the **Input Value** column (**Emma**) and identifies the middle position. Since the string has an even number of characters (4), the action extracts the character at the mid + 1 position.

**Process:**

* **String Length** = 4
* **Middle (String Length/2)** = 4 ÷ 2 = 2
* **mid + 1** = 2 + 1 = 3 → Character at position 3 is **“m”**

The extracted middle portion (m) is stored in the **{Mid String}** variable.

#### **Knowledge Bites:**&#x20;

Here are some examples of different string scenarios:

| String               | Input Value      | Result |
| -------------------- | ---------------- | ------ |
| Text Strings         | Automation       | a      |
| Numeric Strings      | 123456           | 4      |
| Special Character    | <abc@domain.com> | a      |
| Alphanumeric strings | ID2025           | 0      |
| Even-Length String   | User             | e      |
