# Script Type Function Block: Commands The script in a [Script Type Function Block](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) consists of a series of commands that instruct Vehicle Spy to perform certain actions. Each step in the script consists of one command, a set of parameters (if needed) and an optional comment. Table 1 contains a list of all of the available commands for function block scripts. Each row has a short description of the command and the parameters associated with it, and includes a link to a page containing full details. **Table 1: Function Block Script Commands** | **Command** | **Description** | **Parameters (Value Column)** | | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | [**Clear History**](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-clear-history) | Clears the message history. | -- | | [**Clear Stats**](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-clear-stats) | Resets the statistical data for messages or networks. | Selection of whether to clear stats for one message, stats for one network, or all stats. | | [**Comment**](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-comment) | Documents the script with an explicit comment. | -- | | [**CoreMini Action**](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-coremini-action) | Starts, stops, or downloads [CoreMini](https://docs.intrepidcs.com/vspy-3-documentation/3.9.12/vehicle-spy-main-menus/main-menu-tools/utilities-coremini-console) scripts (**.vs3cmb** files) that run in ICS hardware while disconnected from a computer. | Action to perform, and for a download, the storage medium and CoreMini file to use. | | [**DAQ Action**](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-daq-action) | Starts, stops, calls, saves data from, or waits for the completion of a [VehicleScape DAQ](https://docs.intrepidcs.com/vspy-3-documentation/3.9.12/vehicle-spy-main-menus/main-menu-measurement/vehiclescape-daq) Job. | Action to perform and DAQ job to act upon. | | [**Diag Job Action**](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) | Starts, stops, calls, saves data from, or waits for the completion of the specified [Diagnostics](https://docs.intrepidcs.com/vspy-3-documentation/3.9.12/vehicle-spy-main-menus/main-menu-spy-networks/diagnostics/diagnostics-view) Job. | Action to perform and diagnostic job to act on. | | [**Else**](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-commands-if-else-else-if-end-if) | Marks the end of the commands executed when an **If** or **Else If** expression evaluates as **True**, and the start of those executed when that expression is **False**. | -- | | [**Else If**](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-commands-if-else-else-if-end-if) | Combines an **Else** and **If** statement.
