# Script Transformation Editor (Input Columns Page)
  Use the **Input Columns** page of the **Script Transformation Editor** dialog box to set properties on input columns.  
  
> [!NOTE]  
>  The **Input Columns** page is not displayed for Source components, which have outputs but no inputs.  
  
 To learn more about the Script component, see [Script Component](data-flow/transformations/script-component.md) and [Configuring the Script Component in the Script Component Editor](extending-packages-scripting/data-flow-script-component/configuring-the-script-component-in-the-script-component-editor.md). To learn about programming the Script component, see [Extending the Data Flow with the Script Component](extending-packages-scripting/data-flow-script-component/extending-the-data-flow-with-the-script-component.md).  
  
## Options  
 **Input name**  
 Select from the list of available inputs.  
  
 **Available Input Columns**  
 Using the check boxes, specify the columns that the script transformation will use.  
  
 **Input Column**  
 Select from the list of available input columns for each row. Your selections are reflected in the check box selections in the **Available Input Columns**table.  
  
 **Output Alias**  
 Type an alias for each output column. The default is the name of the input column; however, you can choose any unique, descriptive name.  
  
 **Usage Type**  
 Specify whether the Script Transformation will treat each column as `ReadOnly` or `ReadWrite`.
