Process	Choose this process for...
Change Labels	Creating, removing, or changing the labels for one or more variables in a SAS data set
Change Lengths	Changing the lengths of variables in a SAS data set Tip : Reduce disk space and computational time by shortening long character variables . Note : This process does not change the length of numeric variables .
Rename	Renaming one or more primary data variables in a tall data set, and creating a new Experimental Design Data Set (EDDS) to accompany it
Reorder	Rearranging the column order in a data set Tip : This is especially useful for reorganizing a data set formed by merging two or more disparate data sets.
Filter Wide Columns Based on Tall Rows	Removing columns from a wide data set based on a filter specified using variables from the corresponding tall data set to filter its rows
Combine Columns	Combining columns of a tall data set together, computing a summary statistic, and creating an accompanying reduced EDDS Example : This process can be used to average and combine replicate runs of data from an experiment into one column.
Statistics for Columns	Computing a variety of summary statistics for variables in a SAS data set
Transform	Modifying a SAS data set by performing a mathematical transformation on all specified variables
