Only Numbers

-----------------------------------

How can I restrict in Turing so that the user can only enter numbers? Also the user can use backspace as well

Thanks

var dir : string (1)
loop
    getch (dir)
    if index ("0123456789", dir) not= 0 or dir=chr(8) then
        put dir ..
    end if
end loop
