Base SAS 9.1 Procedures Guide, Volumes 1, 2, 3 and 4

Overview

Several statements are available and have the same function in a number of base SAS procedures. Some of the statements are fully documented in SAS Language Reference: Dictionary , and others are documented in this section. The following list shows you where to find more information about each statement:

ATTRIB

• affects the procedure output and the output data set. The ATTRIB statement does not permanently alter the variables in the input data set. The LENGTH= option has no effect. See SAS Language Reference: Dictionary for complete documentation.

BY

• orders the output according to the BY groups. See BY on page 58.

FORMAT

• affects the procedure output and the output data set. The FORMAT statement does not permanently alter the variables in the input data set. The DEFAULT= option is not valid. See SAS Language Reference: Dictionary for complete documentation.

FREQ

• treats observations as if they appear multiple times in the input data set. See FREQ on page 61.

LABEL

• affects the procedure output and the output data set. The LABEL statement does not permanently alter the variables in the input data set except when it is used with the MODIFY statement in PROC DATASETS. See SAS Language Reference: Dictionary for complete documentation.

QUIT

• executes any statements that have not executed and ends the procedure. See QUIT on page 63.

WEIGHT

• specifies weights for analysis variables in the statistical calculations. See WEIGHT on page 63.

WHERE

• subsets the input data set by specifying certain conditions that each observation must meet before it is available for processing. See WHERE on page 68.
