# Command Window
  Use the **CommandWindow** to run commands, such as debug and edit commands, against the code in the [!INCLUDE[ssDEnoversion](../../includes/ssdenoversion-md.md)] Query Editor window that is currently being debugged. You must be in debug mode to use the **Command Window**. The [!INCLUDE[tsql](../../includes/tsql-md.md)] debugger supports many of the commands that are also supported in the [!INCLUDE[msCoName](../../includes/msconame-md.md)] [!INCLUDE[vsprvs](../../includes/vsprvs-md.md)] **Command** window. For more information, see [Visual Studio Command Window](https://go.microsoft.com/fwlink/?LinkId=112007).
