You can, if you want, just downcase the string as
(define (lower-case-char char)
  (if (not (char? char))
      (error '......))
  (integer->char (let ([i (char->integer i)])
                   (if (<= 65 i 80) ; not sure about the numbers, you 
should check
                       (+ i 32)
(define (lower-case str)
  (if (not (string? str))
      (error '.......))
  (list->string (map lower-case-char (string->list str))))
(eval (string->symbol (lower-case "AA")))
