By default, the PROC FREQ in the code below produces an output object named CrossTabFreqs and the PROC MEANS produces an output object named Summary.
<insert code here>
proc freq data = Work.AE;
table USUBJID*AEPTCD;
run;
proc means data = work.LB max;
class USUBJID;
var STUDYDY;
run;
Which code segment can be added prior to the PROC FREQ step to ensure that PROC MEANS produces its output object but PROC FREQ produces no output object?
