Next code distinguish between upcase and lowcase letters.

Use the same method for counting:

data want;
   x='ABCDefghiJKLMNopqrs';
   do i =1 to length(x);
        char = substr(x,i,1);
        if char = upcase(char) then put CHAR ' is an upcase letter';
                               else put CHAR ' is a lowcase letter';
  end;
run;

Do you need something like this:

data _null_;
x='ABC123ef';
    /* k..() functions work with utf-8 */
l = klength(kcompress(x,,"kl"));
u = klength(kcompress(x,,"ku"));
put _all_;
run;

Well, have you tried the suggested solution? If you have requirements for the output, show them. We can't read your mind 😉

In my code the variable L contains count of lower case letters, and the variable U contains count of upper case letters.
