How to loop/repeat function?

It sounds like you want to run a function that updates a number every 60 seconds, and you want this process to repeat indefinitely. To achieve this, you can use a loop along with a delay function. Since you haven’t specified a programming language, I’ll provide a general pseudocode example that you can adapt to your specific language:

while true:  // Infinite loop
    // Call your function to update the number
    updateNumber()

    // Pause the loop for 60 seconds
    sleep(60 seconds)
