Parameters | Utilities | Delete rows satisfying this expression

Delete rows satisfying this expression
Specify a valid SAS logical expression in terms of the statistics that you specified. This expression is evaluated for every row. Any rows in which this expression evaluates to true are deleted.
For example,
MEAN GT 5 and VAR LT 3
deletes all rows with mean greater than 5 and variance less than 3. Every statistic referenced in this expression must be selected on the Statistics tab.
When you have specified grouping variables, the SAS variable names of the computed statistics columns are numbered sequentially (for example, MEAN1, MEAN2, MEAN3, ...). The SAS labels for these variables are not numbered sequentially, but rather consist of the levels of the grouping variables.
