To tide you over until you get the book, how about:

-- this asks for input and just compares it to a value.

ask "please type a number"
if it is 123 then
  answer "you got it!"
else
  answer "try again"
end if

-- here's a version that loops until you get the right answer
-- the repeat / end repeat construct is the equivalent
-- of the "do while" construct you'll find elsewhere

repeat until x is 123
  ask "please type a number"
  put it into x
end repeat
