Example:Use the GO TO statement as shown here.

• In this example, if the condition is true, the GO TO statement instructs SAS to jump to a label called ADD and to continue execution from there. If the condition is false, SAS executes the PUT statement and the statement that is associated with the GO TO label:

· data info;

· input x;

· if 1<=x<=5 then go to add;

· put x=;

· add: sumx+x;

· datalines;

· 7

· 6

· 323

;

Because every DATA step contains an implied RETURN at the end of the step, program execution returns to the top of the step after the sum statement is executed. Therefore, an explicit RETURN statement at the bottom of the DATA step is not necessary.

• If you do not want the sum statement to execute for observations that do not meet the condition, rewrite the code and include an explicit return statement.

· data info;

· input x;

· if 1<=x<=5 then go to add;

· put x=;

· return;

· /* SUM statement not executed */

· /* if x<1 or x>5 */

· add: sumx+x;

· datalines;

· 7

· 6

· 323

;
