# Part 2 - Create Function Block to Request and Save Data

### 1. Open Function Blocks View:

From the main menu select **Scripting and Automation> Function Blocks**.

### 2. Create a Function Block:

Click the **+ button** and select **Script** to create a new Script type function block. Change the description of the function block to something more descriptive like **Check Codes and Log Them to a File**.

### 3. Write the Script:

Now a script needs to be entered. For this task 4 steps will be needed (Table 1). For **Diag Job Action** double clicking on the **Value** cell will allow selection of the diagnostic job to act on and how to act on it. For more information on this command see the help for the [Diag Job Action command](https://docs.intrepidcs.com/vspy-3-documentation/3.9.12/vehicle-spy-main-menus/main-menu-scripting-and-automation/function-blocks/function-blocks-types/script-type-function-block-commands/script-type-function-block-command-diag-job-action).

### Configure the Start Setting:

On the **Start** tab select **Manual Start**. This allows the Script function block to be started using Graphical Panel controls that will be set up in the next part of this tutorial.
