Hi, all

  I'm just wondering how can I make my string upper-case?
  I have found the string-upper-case? function (http://docs.plt-
scheme.org/htdp-langs/advanced-prim-ops.html#%28def._%28%28lib._lang/
htdp-advanced..ss%29._string-upper-case~3f%29%29), but it just tests
the strings.

Thanks in advance.
