Syntax

CALL SORTN(variable-1<, ..., variable-n>)

The values of variable are sorted in ascending order by the CALL SORTN routine.

The CALL SORTN routine is used with numeric variables, and the CALL SORTC routine is used with character variables.

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

data _null_;
   array x(10) (0, ., .a, 1e-12, -1e-8, .z, -37, 123456789, 1e20, 42);
   call sortn(of x(*));
   put +3 x(*);
run;

SAS writes the following output to the log:

   . A Z -37 -1E-8 0 1E-12 42 123456789 1E20
