Your request is unclear to me. What else but number entry would you expect ?
Can you give a sample code of what you're trying to do ?

He wants to detect if numbers are typed or if letters are typed. On the 41, Flag 22 is set (and 23 is reset) when the user types a number in response to an input statement. Flag 23 is set (and 22 is reset) if the user types a letter instead.
