# Script types

![Modified Java Script Value step Script Types dialog](/files/eHfCvgtwHRMYp4hROXVv)

You can right-click a tab in the Java script pane to open a context menu with the following commands:

* `Add new`: Add a new script tab.
* `Add copy`: Add a copy of the existing script in a new tab.
* `Set Transform Script`: Specify the script to execute for each incoming row. Only one tab can be set as a transform script. The first tab is a transform script by default.
* `Set Start Script`: Specify the script to execute before processing the first row.
* `Set End Script`: Specify the script to execute after the last row has been processed.
* `Remove Script Type`: Specify to not execute the script. The script tab is not removed. To remove a script tab, click the **Close** (X) button and choose **Yes** to delete the script tab.

The icon for the script type displays on the tab to denote the type of script on the tab. To rename a script tab, right-click the tab name in the **Transform Scripts** section of the **Java script functions** pane, choose **Rename**, and enter the new name.
