Purpose of DO Loops
DO
loops process groups of SAS statements repeatedly, reducing the
number of statements required in repetitive calculations.
Syntax of Iterative DO Loops
To
construct an iterative DO loop, specify an index variable and the
conditions that will execute the loop. These conditions include a
start value for the index variable, a stop value, and an increment
value. Start, stop, and increment values can be any number, numeric
variable, or SAS expression that results in a number.
DO Loop Execution
During each iteration of a DO loop, statements within the loop execute. Once the loop's index value exceeds the stop value, the DO loop stops, and processing continues with the following DATA step ...
