Examples

The following example sorts the character variables in the array in ascending order.

data _null_;
   array x(8) $10
      ('tweedledum' 'tweedledee' 'baboon' 'baby'
       'humpty' 'dumpty' 'banana' 'babylon');
   call sortc(of x(*));
   put +3 x(*);
run;

SAS writes the following output to the log:

   baboon baby babylon banana dumpty humpty tweedledee tweedledum
