The command-line argument is a kind of parameter supplied to the program when it is invoked. Some applications can receive/take parameters from the command line. These kinds of applications are configurable with appropriate parameters from Single Connect. So, we can start, call these applications with parameters. Single Connect executes these kinds of applications with preconfigured parameters through the RDP protocol. Hence all the information, including the sensitive data, is transmitted inside the RDP protocol securely.

To configure Parametric Solution:

1. Navigate to **Device Management** > **Device Group**.
2. Right-click the device group you want to edit and select **Allow Remote Application**.
3. Check both the **Allow** and **Auto Login** checkboxes.
4. Click the **Set Auto Login Properties** button and fill in the required fields with the information shown in the image below.
5. Select** Use Parameters** and then configure accordingly.

The figure above shows that the WinSCP application receives some parameters such as username, password, and device IP. This syntax is specific to the WinSCP application. Other applications can have similar syntaxes, so we can define the applications’ parameters and fill the necessary fields as we do in the OCR section. OCR and Parametric solutions use a common screen, and configurations are the same.
