The SORTEQOP option specifies whether
the host sort utility accepts the EQUALS option. (The EQUALS option sorts
observations that have duplicate keys in the original order.) If the utility
does accept the EQUALS option, then SORTEQOP causes the EQUALS option to be
passed to it unless you specify NOEQUALS in the PROC SORT statement. If NOSORTEQOP
is in effect, then the EQUALS option is not passed to the host sort utility
unless you specify the EQUALS option in the PROC SORT statement.
Note that equals processing is the default for PROC
SORT. Therefore, if NOSORTEQOP is in effect, and if you did not specify EQUALS,
then the host sort interface must do additional processing to ensure that
observations with identical keys remain in their original order. This requirement
of the host system might adversely affect performance.
For information about specifying the appropriate setting for the SORTEQOP
option, see the documentation for your sort utility.
