SAS(R) 9.1.3 Companion for z/OS

You can see the values of the preceding options by submitting:
proc options group=sort; run;
PROC SORT Statement Options
Procedures under z/OS SORT Procedure 337
The following host-specific sort options are available in the PROC SORT statement
under z/OS in addition to the statement options that are available under all host
operating environments. The list includes the portable EQUALS option because it has
aspects that are specific to z/OS.
DIAG
passes the DIAG parameter to the sort utility. If the utility supports this option,
then it will produce additional diagnostic information if the sort fails.
EQUALS
passes the EQUALS parameter to the sort utility program whether or not the sort
utility supports it. SAS software defaults to EQUALS by passing the parameter to
the utility if the SAS system option SORTEQOP is in effect.
LEAVE=n
specifies how many bytes to leave unallocated in the region. Occasionally, the
SORT procedure runs out of main storage. If this happens, rerun the job and
increase the LEAVE= value (which has a default value of 16000) by 30000.
LIST | L
provides additional information about the system sort. Not all sort utilities
support the specification of the LIST option; they may require that it be specified
when the sort utility is generated or installed. This option is the default action if
the SAS system option SORTLIST is in effect. Also, this option overrides
NOSORTLIST if it is in effect.
MESSAGE | M
prints a summary of the system sort utility’s actions. This option is the default
action if the SAS system option SORTMSG is in effect. Also, this option overrides
NOSORTMSG if it is in effect. MESSAGE is useful if you run PROC SORT and
the SAS log prints a message indicating that the sort did not work properly.
Explanations of the message can be found in the IBM or vendor reference manual
that describes your system sort utility.
SORTSIZE=n | nK |nM |nG | MAX | SIZE
specifies the maximum virtual storage that can be used by the system sort utility.
If not specified, the default sort size is given by the SAS system option
SORTSIZE=.
SORTWKNO=n
specifies how many sort work areas PROC SORT allocates. If not specified, the
default is given by the SAS system option SORTWKNO=.
TECHNIQUE=xxxx |T=xxxx
specifies a four-character sort technique to be passed to the system sort utility.
SAS does not check the validity of the specified value, so you must ensure that it
is correct.
Specifying the SORTSEQ= Option with a Host Sort Utility
The SORTSEQ= option enables you to specify the collating sequence for your sort. For
a list of valid values, see the Base SAS Procedures Guide.
