SORT

CMS specifics:

SORT procedure statement options

Details

Under CMS, the SORT procedure uses the EBCDIC collating sequence. For general information about the SORT procedure see SAS Procedures Guide.

You can direct the SORT procedure to use either the SAS sort program, available under CMS and under all other operating environments, or a sort utility specific to CMS, or you can allow SAS to choose the best sort program to use. You make this choice with the SORTPGM= system option. See System Options for details on the SORTPGM= option and the other system options that affect the SORT procedure. These system options include the following:

FILSZ

specifies whether the SORT procedure being used supports the FILESIZE parameter.

SORTEQOP

specifies whether the SORT procedure being used supports the EQUALS parameter.

SORTLIB=

specifies the TXTLIB to be made global for PROC SORT use.

SORTLIST

indicates whether SAS is to pass the LIST parameter to the SORT package being used (to request additional information about the sort process).

SORTMSG

indicates whether SAS is to indicate to the SORT package to write all messages or just those that are critical.

SORTSIZE=

specifies what value SAS is to pass to the SORT package being used to indicate the maximum virtual storage to be used.

SORTSUMF

indicates whether the SORT package being used supports the SUM FIELDS= parameter.

SORT Procedure Statement Options

The following host-specific sort options are available in the PROC SORT statement under CMS in addition to the sort options available on all hosts. Note that the list includes the portable EQUALS option because it has aspects specific to CMS.

DIAG

passes the DIAG option to the host sort program. The interpretation of the DIAG option is entirely up to the host sort program; it has no effect on SAS. This option is recognized only when the system option SORT31PL is in effect.

EQUALS | NOEQUALS

passes the EQUALS or NOEQUALS option to the host sort program regardless of the setting of the SAS system option SORTEQOP.

LEAVE=n

adjusts the value of the storage parameter passed to the host sort program.

If SORTSIZE=SIZE is in effect, SAS estimates the size of the largest contiguous block of available storage, then subtracts the values of the system option LEAVE= and of the SORT procedure statement option LEAVE=, and passes the resulting value to the host sort. Note that the calculations are based on the size of the largest block of storage, whether it is above or below the 16M line. If the host sort is AMODE 24, however, SAS will consider only storage below the line. Some host sorts may allocate work storage only below the line even if they are AMODE 31, in which case the size estimated by SAS can be misleading.

If SORTSIZE=n is in effect, the LEAVE= value is subtracted from the SORTSIZE value.

For other values of SORTSIZE=, the LEAVE= option has no effect.

LIST L

passes the LIST option to the host sort program. The interpretation of the LIST option is entirely up to the host sort program; it has no effect on SAS. This option is ignored unless the system option SORT31PL is in effect.

MESSAGE | M

passes the PRINT=ALL option to the host sort program. The MESSAGE option is useful if you run PROC SORT and the SAS log prints a message 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 | MAX | SIZE SIZE=n | nK | MAX | SIZE

specifies the maximum virtual storage that can be used by the system sort utility. If not specified, the default is given by the SORTSIZE= SAS system option.
