If you want to be able to examine the repeated records, you could use something like the following:

data temp; input var1 $ var2; datalines; A 1 A 1 B 1 C 1 B 1 B 2 D 2 A 2 D 3 D 3 E 1 E 1 E 3 ; RUN;

proc sort data=temp; by var1 var2; run;

data doubles; set temp; by var1 var2; if not (first.var2 and last.var2); run;

Hope this is helpfull,
