Details
You can direct the SORT procedure to use either the SAS sort program, which is
available under z/OS and under all other operating environments, or a sort utility that
is specific to z/OS. You can also use the SORTPGM= system option to tell SAS to choose
the best sort program to use. (See “SORTPGM= System Option” on page 507.)
