Third question: Isn't this the same question as you asked in the other thread?
Please don't post the same question multiple times. To get a good response to your question post: test data, in the form of a datastep that covers your actual data and any differences - we can only work with what you give us. Also post, what you want the output to look like, then any additional logic which may help. Looking at your latest post, my post originally that was ignored should give you the result you want:
data have; input id term grade $ subj num; datalines; 10 2002 D 332 1 10 2002 A 333 2 11 2005 C 232 1 11 2005 A 232 2 11 2005 B 232 3 11 2005 C 232 4 15 2010 A 130 1 15 2010 B 130 2 15 2010 C 130 3 ; run; data want (keep=id term subj); length res $10; set have; retain res; by id term; if first.term then res=""; res=cats(res,grade); if last.term and index(res,"ABC")>0 then output; run;
