Iterative DO loops
- [Instructor] To eliminate having to type repetitive code, you can use the iterative DO loop. The DO loop starts with a DO statement, and ends with an END statement. During data step execution, the iterative DO loop processes statements between the DO and END statements repetitively. index-column names a column whose value controls the execution of the DO loop. The value of this column is incremented at the end of each pass through the DO loop. The index-column is included in the output table unless you drop it. In this example, Year is the index-column. We won't drop the index-column in the code because we want to have a column for year. Execution of the DO loop is based on the start value and stop value. Start is a number or numeric expression that specifies the initial value of the index-column. Stop is a number or numeric expression which specifies the value that the index-column must exceed to stop the execution…
