Compare what user entered to the specific value. If they mismatch - ask again. Also there are several utility methods in %Prompt class for number/yes-no/etc input:

GetNumber
GetString
GetYesNo
GetArray - Prompt for a number or entry in a displayed menu. Returns the selected item.
GetMenu - Prompt for a number in a displayed menu.
GetMore - Prompt for More or Quit.

For example:

do ##class(%Prompt).GetYesNo("Enter Yes or No:", .result)

User can input only Yes (Y) or No (N). result variable would hold 1 or 0.

You can also check %Prompt code and write something based on that.
