SAS - proc report - column statement

The column and the by statement defines which variables from the input data set is used.

Variables that are not listed in the column and by statements are not used.

The variables can the also be used in the compute block.

For each variable, a respective define statement should be used. If not, sAS provides a default define statement.

proc report can be run without column statement. In this case, SAS creates a default column statement with the variables of the input data set.

In order to see what defaults proc report generates, the list option can be used.
