Hello, I'm Rdp060707. An edit you recently made to Coupling (computer programming) seemed to be a test and has been removed. If you want more practice editing, the sandbox is the best place to do so. If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page. Thank you. Rdp060707&#124;talk 05:18, 2 August 2021 (UTC)
