Proc SQL

And @Hakob , proc rank also works:

data salary;
   input id salary1-salary4;
   datalines;
1 12 34 50 70
2 34 45 52 12
3 43 12 36 22
4 32 29 80 37
5 21 10 90 43
;
run;
proc print data=salary;run;

proc rank data=salary out=salrk descending;
   var salary1-salary4;
   ranks sal1rk sal2rk sal3rk sal4rk;
run;
proc print data=salrk;run;

And @Hakob , there is a technique of proc means can also output top 3 values using output out=top3list(idgroup(max(var) out[3]) (I cannot remember or identify all the necessary and basic and correct syntax for it, it's just part of the statement), but I would not recommend to use this technique due to the above complexities and difficulties.
