If SORT31PL is in effect,
a 31-bit extended parameter list is used to invoke the host sort utility.
If NOSORT31PL is in effect, a 24-bit parameter list is used.
If SORT31PL is specified,
then the SORTOPTS system option should also be specified. Also, because
sorts that currently support a 31-bit parameter list also support
the EQUALS option, the SORTEQOP system option should be specified
in order to maximize performance.
For information about
specifying the appropriate setting for the SORT31PL option, see the
documentation for your sort utility.
