1. Select the command in the Enter a command text box and click the Add parameter button to add a parameter to a command. You also can select and right-click the command, and select Add parameter from the shortcut menu.

Note   If you want to reuse a parameter from a previous command, you can right-click a command and use Link to input from the shortcut menu to create a new instance of a parameter you entered previously. You also can copy a parameter from a previous command by selecting the parameter and pressing the <Ctrl-C> keys. You can paste the parameter into a new command by pressing the <Ctrl-V> keys.

2. Enter a default value for the parameter in the Test value text box.
3. Enter a name for the parameter in the Parameter name text box. You use this name to reference the parameter in the application.
