LINE statements cannot be conditionally executed; they will always print out. However, the text that is printed in the LINE statement can be controlled.

In a compute block, use an IF statement to populate a text string with the desired values. Use this text string in the LINE statement:

   PROC REPORT NOWD DATA=sashelp.class;
     col age weight;
     DEFINE age / ORDER;
     BREAK AFTER age / SUMMARIZE;

     COMPUTE AFTER age;
       LENGTH text $ 30;
       IF age GE 16 THEN text='drivers beware';
       ELSE text='along for the ride';
       LINE text $30.;
     ENDCOMP;

   RUN;
