Look at the example:

data _null_;
   a1 = 10;
   a2 = 5;
   a3 = .;
   y = min(a1,a2,a3);
   put y =;
   if whichN(y, a1,a2,a3) then xx ='recur';
   put xx =;
run;

COALESCE() can come in handy.

Read through the function list, the best way to know what options you have

if cmiss(of date:) = 0 then
    edur = choosec(whichn(min(of date:), of date:),"recur","recur","recur","death");
