+ / * &

range operators
: - give me a range
, - give me union
 space bar - give me the intersection

Function IsLess(A as string, B as string) as boolean
  if a < b then
    isless = true
  else
    IsLess = false
  end if
End Function

1. take in the input
2. get its code
3. then add 32
4. then get its char

HW - not to collect, yet:
only perform this conversion when it is in the appropriate range. use char, code, if, and
