**Block** is a function used to add data to prevent tracking. Tracking values (magenta colored) are converted to stored values (white colored).

To execute this keyword type **Block** or the shortcut **Blo** into the command line. 

## Syntax

## Options

To get a list of all available options for the keyword Block in the command line feedback window type the following into the command line:

\[Channel]> Block /?

The keyword Block has the following options:

| Option         | Shortcut | Option value    | Description              |
