Sorts observations in a SAS data set according to the values of
one or more variables
||available OS/390 sort utilities and
SORT procedure statement options; host-specific SAS system options
You can direct the SORT procedure to use either the
SAS sort program, which is available under OS/390 and under all other operating
environments or a sort utility that is specific to OS/390. You can also use
the SORTPGM= system option to tell SAS to choose the best sort program to
use. (See SORTPGM=.)
The following SAS system options also affect any sorting
that is done by SAS:
|*Options marked with an asterisk (*) are either portable
or portable with host specifics. For information on these options, begin with
SAS Language Reference: Dictionary.
You can see the value of the preceding options by submitting:
proc options group=sort; run;
The following host-specific sort options are available in the
PROC SORT statement under OS/390 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 OS/390.
- 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.
- passes the EQUALS parameter to the sort
utility program whether or not the sort utility supports it. The SAS System
defaults to EQUALS by passing the parameter to the utility if the SAS system
option SORTEQOP is in effect.
- 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=.
- specifies how many sort work areas PROC
SORT allocates. If not specified, the default is given by the SAS system option
- 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
