Do in SAS?

The DO statement is the simplest form of DO group processing. The statements between the DO and END statements are called a DO group. You can nest DO statements within DO groups. Note: The memory capabilities of your system can limit the number of nested DO statements you can use. For details, see the SAS documentation about how many levels of
